11:28 p.m. ET: We'll leave you with one final video, of Matt Kenseth pulling away for his third win of the season. Good night!
10:59 p.m. ET: And Miss Sprint Cup (@MissSprintCup) is the first to post a picture from Victory Lane:
10:50 p.m. ET: Some more reaction on social media:
10:44 p.m. ET: What a great weekend for Joe Gibbs Racing. Matt Kenseth wins for the third time this season. Some reaction:
10:39 p.m. ET: Matt Kenseth is in position to win this race.
"@JoeGibbsRacing: Kenseth passes Busch, takes the lead in the Husky Tools Toyota."
10:36 p.m. ET: Here's video of the incident that caused an earlier caution:
10:31 p.m. ET: Good point from NASCAR.com's Alan Cavanna. (Kyle Busch took blame for spinning out Kahne at Daytona and Talladega):
"@CopaCavanna: That's three times this year that Kasey and Kyle have been involved in some sort of incident."
10:24 p.m. ET: Kasey Kahne and Kyle Busch completed a remarkable stretch of racing that ended when Kahne got into the wall:
10:19 p.m. ET: The leaders decide to pit under the fourth caution. Here's a sampling of how it went:
"@JoeGibbs Racing: Busch first off pit road again! Hamlin out 3rd, Kenseth out 4th. Killer pit stops crews!!! Pit Crew coaches Lepp & Alepa gotta be proud."
"@99_RFRracing: Came in under caution for fresh tires, gained 3 spots now P5 on the restart"
"@StewartHaasRcng: Stewart pits for 4 tires, fuel and track bar adjustment. Will restart P11. 16 cars on lead lap. 35 laps to go."
10:14 p.m. ET: Very nice use of Vine by JTG Daugherty Racing (@NASCAR47), which was right in front of David Ragan when his engine overheated.
10:11 p.m. ET: The official recording of the third caution, via @NASCARStats:
"Caution 3: Accident on frontstretch involving Brad Keselowski, Casey Mears and Kurt Busch; laps 313-317, 18 total caution laps #NASCAR"
10:09 p.m. ET: The top four drivers stayed out on the track during that caution; that includes two Hendrick Motorsports drivers. A most interesting question:
10:06 p.m. ET: Third caution comes out quickly when Casey Mears gets into the wall; Kurt Busch was also affected:
9:59 p.m. ET: The biggest question for drivers is whether or not they'll have enough fuel the rest of the way. Kasey Kahne appears to be in good shape:
9:52 p.m. ET: The second caution of the race was brought out when Regan Smith spun out. It happened right as green-flag pit stops were underway. How it impacts certain drivers:
"@StewartHaasRcng: Caution is out on lap 301. Great break for Stewart. P8"
9:50 p.m. ET: Some pit strategy from Kevin Harvick, who's been in or near the top five all night.
"@JoeGibbsRacing: 48 now 0.7 sec behind Kyle. 77 laps to go"
9:42 p.m. ET: We're in the midst of another strong showing from Hendrick Motorsports at Darlington Raceway.
9:40 p.m. ET: One Busch continues to speed away, the other continues to struggle. From David Caraviello:
"@dcaraviello: Pole sitter Kurt Busch, in 12th place, just lapped by brother Kyle."
9:38 p.m. ET: Making his 700th career Cup start, Jeff Gordon is near the top five. The latest pit stop made his car better in Turns 1 and 2, but he's slightly worse in Turns 3 and 4 now.
9:34 p.m. ET: We haven't heard much from last week's winner, David Ragan, tonight. The Front Row Motorsports driver has had a rough go at Darlington Raceway.
9:32 p.m. ET: And now, Kurt Busch is apologizing to his team over the radio for his showing tonight (the No. 78 is currently 11th). His team tells him to stay positive:
9:26 p.m. ET: Clint Bowyer had to serve a pass-through penalty for driving off with his gas can still in. He apologized to his team, which took it in stride ...
9:21 p.m. ET: Tony Stewart had cracked the top 10 prior to coming in for fuel. He's only had one top-10 this season.
"@StewartHaasRcng: Another round of green flag stops. Stewart pits on lap 240 for 4 tires, fuel and LR wedge adjustment."
9:18 p.m. ET: Kasey Kahne, running third at the time of this incident, is having a tough time hearing his team over the radio. Alan Cavanna:
"@CopaCavanna: Kahne trying to tell team he is loose. Team asks 'what's loose?' and he says he can't understand them. They're trying to bring him in soon"
9:14 p.m. ET: A good night is continuing to turn bad for Kurt Busch. He's slapped the wall in his No. 78 Chevrolet. Alan Cavanna was listening to his scanner:
"@CopaCavanna: Kurt got the 'ol Darlington stripe'. Tells crew to make sure they fix right front fender."
9:10 p.m. ET: The four Hendrick Motorsports drivers are all in the top eight, with Jimmie Johnson leading the charge at second. You can follow the race with our live leaderboard here.
9:06 p.m. ET: Sounds like Greg Biffle has a good car, but he's out of the top 15 as it stands. Via 3M Racing:
8:59 p.m. ET: Brad Keselowski is almost in position to be the beneficiary, should a caution come out. He went down two laps earlier with a vibration issue. From Alan Cavanna:
8:54 p.m. ET: Richard Childress Racing has two drivers in the top 12 thus far, much like it has two drivers in the top in the points standings. The report:
8:50 p.m. ET: Halfway home! The Busch brothers have dominated thus far, leading 180 of the first 184 laps.
8:47 p.m. ET: A nice, newsy update from NASCAR Stats:
8:41 p.m. ET: This is the race in which Matt Kenseth does not have suspended crew chief Jason Ratcliff, but it might not matter. Kenseth running well -- again. See below:
8:35 p.m. ET: A frustrated Kurt Busch, who has led 69 laps, is dropping down the top 10. He's using some colorful analogies to describe his displeasure. NASCAR.com's Alan Cavanna:
"@CopaCavanna: About 20 laps ago, Kurt described the surface as 'linoleum', now it's like 'ice'."
8:34 p.m. ET: Carl Edwards had car issues earlier, but they are mostly ironed out now. The No. 99 is one of 18 cars on the lead lap.
"@99_RFRracing: The 99 crew has been working on adjustments most of the night, Carl is still a little tight into turn 4 - P13"
8:30 p.m. ET: Denny Hamlin took two tires during a pit stop under yellow and came out of pit road second. He's lost ground, but this was a strategic move. From Joe Gibbs Racing:
8:24 p.m. ET: After more than 100 laps, we have our first caution of the evening.
8:17 p.m. ET: Another beauty from Zack Albert (@zack_albert):
8:05 p.m. ET: NASCAR.com's Alan Cavanna is listening to Kurt Busch on the radio. The driver isn't happy.
8:03 p.m. ET: Jeff Gordon took time with a young fan prior to making his 700th career Cup start. NASCAR.com's Zack Albert (@zack_albert) sends this via Twitter:
7:36 p.m. ET: Kurt Busch gives up the lead to brother Kyle Busch in order to pit. And his lead was big.
From David Caraviello: "@dcaraviello: Kurt Busch had a 2.139-second lead on brother Kyle before coming into the pits."
7:26 p.m. ET: Kurt Busch content to let his driving do the talking, for now.
7:22 p.m. ET: Lots of official accounts on Twitter reporting radio chant. And most drivers say their cars are tight. For example, Greg Biffle (@163MTEAM), Jeff Gordon (@JeffGordonWeb) and Dale Earnhardt Jr. (@MikeDavis88).
7:17 p.m. ET: Good information from the Joe Gibbs Racing Twitter account.
7:15 p.m. ET: NASCAR's official Twitter account (@NASCAR) tweets: "PHOTO: Feel the roar". We feel it.
7:10 p.m. ET: History is at hand for Jeff Gordon, but the driver and his crew remain calm. Via Twitter:
6:56 p.m. ET: Denny Hamlin has no back-up driver tonight. He's starting and plans to finish. His hometown track has a message:
6:53 p.m. ET: Craving information? Giving @NASCARStats a follow. Here's a gem from that account: "@NASCAR Stats: The #BojanglesSo500 is scheduled for 367 laps; 501.3 miles. Pit road speed is 45 mph and the fuel window is 60 laps #NASCAR"
6:41 p.m. ET: With Mother's Day tomorrow, it looks like a good number of drivers brought their moms to Darlington Raceway. Another good picture from Miss Sprint Cup (@MissSprintCup), this one of Dale Earnhardt Jr. and his mother.
6:30 p.m. ET: Looks like Miss Sprint Cup (@MissSprintCup) ran into one of the many Darlington dignitaries. Pro wrestling's Ric Flair is on hand to help introduce the drivers. Flair is hugely popular in his hometown of Charlotte, which is less than 100 miles from the track.
6:25 p.m. ET: Interesting note from NASCAR.com's David Caraviello during driver introductions. Via Twitter: @dcaraviello: Huge cheers for Danica Patrick during pre-race driver introductions at Darlington Raceway. A few boos, but not many.
6:23 p.m. ET: Another component of NASCAR.com, that's live right now -- the race's live leaderboard.

5:51 p.m. ET: To tie the previous two posts together, Darlington Raceway has been a good track for Hendrick Motorsports drivers recently. Last year, Jimmie Johnson's win gave team owner Rick Hendrick his 200th career victory. This year, Jeff Gordon makes his 700th career Cup start. Those are big numbers, folks. And if you missed it, here is a great feature on Gordon by NASCAR.com's David Caraviello.
5:45 p.m. ET: Hey, who says pit crew guys aren't athletes? Check out Jimmie Johnson's crew stretching prior to the race, courtesy of NASCAR's official Twitter account, @NASCAR. For what it's worth, Johnson is the defending race champion.
