When he was 17 years old, Robbie Allison started reading the biography of his late father Davey Allison, penned by his mother and Davey’s widow, Liz. Titled “Full Circle,” Robbie dove into the book as a way to get to know his father, who died tragically when Robbie was not yet 2 years old.

When he got to the chapter of his father’s fatal helicopter crash, Robbie felt a pang of loss, an emotion he didn’t quite comprehend when he was young.

“There I am at the end of his life, and that really took me by surprise,” he said. “I’m just getting into this story and enjoying what I’m reading, and he’s gone. I think it’s very symbolic of his life. There was so much that he had left to accomplish, and it was cut so short. I think that’s something that we all still grieve over.

“When I read that book … I felt like I experienced losing him.”

The process of getting to know their father after his death is strange for Robbie Allison and Krista Allison Sheinfeld, Allison’s children. Sometimes Robbie goes back to Hueytown, Alabama, to visit his father’s grave. He doesn’t usually tell anyone he’s going — he goes to sit and talk to his dad.

Like any son, he yearns for a father’s listening ear.

“It’s always a private event … and it’s usually kind of spur of the moment,” Robbie said. “I just decide at 11 p.m. one night I’m going to drive four hours and go down there and visit him. But it’s always during momentous times like that, when I just want to talk to him, and kind of share my own life with him.”

Like Robbie, Krista has few memories of her father; most come from photos or videos, as she was also young (3 years old) when he passed.

But one of Davey’s distinct features remains with her.

“I know Robbie and I have talked about this. We remember the way that he smelled,” she said. Both Robbie and Krista say they associate the smell of charcoal with their father.

“I do remember his voice,” she continued. “Not just from videos and from TV, but he had such a memorable voice. I do remember that so clearly and those are the memories I like to keep with me that I try not to let the TV and video memories overpower too much.”

Family members have helped paint the picture of Davey for Robbie, too. But finishing the biography was the final, sometimes painful, part in getting to know his father.

“They say there’s the five stages of grief and I went through all five of them just from reading that biography,” Robbie said. “When I got to the other side of those five steps, and grief is a lifelong process, but when I had felt like I had properly processed grieving over that loss, I was glad that I did it.

“I felt like that was something that as much as I missed out on knowing him as a dad, I felt like I missed out on grieving losing him. Being able to do that, I think, allowed me to move into my adulthood and feel like I’d gotten to know him, and I had lost him, and life goes on.”

Davey Allison’s trademark toughness was as much a part of his lore as his triumphs. Time and again, the future Hall of Famer righted himself after being knocked down.

Allison’s grit was a prominent part of his final full season in 1992, when he had his closest brush with NASCAR’s premier series championship. Allison fought through multiple injuries, twice being airlifted from tracks, yet still started every race.

In a particularly perilous stretch from spring into summer, Allison’s mettle was tested with a flurry of severe crashes. In April, he suffered rib and lower back injuries in a crash at Bristol Motor Speedway. The following week, Allison suited up with a flak jacket and a reinforced seat to ease the pain, then fought through late-race leg cramps to win at North Wilkesboro Speedway.

In those days, the race winner was routinely brought to the press box above the grandstands to meet the media. Allison’s trip through the bleachers attracted a crowd, which waited patiently outside the track’s rickety stairs for his availability to end. Allison, still reeling from the strain of 400 laps, signed autographs for every fan in line, asking only for a chair from the speedway staff.

One month later, Allison won again at NASCAR’s All-Star Race, the first held under the lights at Charlotte Motor Speedway. The price was costly; Allison crashed after contact with Kyle Petty under the checkered flag, making heavy contact with the outside retaining wall.

Allison suffered a concussion and a bruised lung. He completed all 400 laps the following week in the Coca-Cola 600 at Charlotte to maintain his series points lead.

The hardest hit of all came two months later at Pocono Raceway. Contact with Darrell Waltrip’s car sent Allison’s No. 28 spinning into a dramatic 11-flip blowover in the infield grass. Allison absorbed a fractured and dislocated right wrist, a broken collarbone, broken right forearm and multiple facial bruises.

“I don’t know how many licks like this our little driver can take,” Larry McReynolds, Allison’s crew chief, told reporters after the race. Remarkably, Allison’s determination to start the following week’s race at Talladega Superspeedway became known in a matter of days.

Allison underwent 4 1/2 hours of surgery on that Pocono Sunday, with plates and screws inserted to address his arm fractures. After a follow-up bone graft operation Thursday, he was released from the hospital Friday and practiced the car the next day, fitted with a special cast to assist in shifting gears. An early caution allowed Allison to give way after five green-flag laps to relief driver Bobby Hillin Jr., who filled in admirably for a third-place finish.

All this occurred while Allison battled through significant facial swelling and dark, bloodshot eyes. “I would take these sunglasses off, but it’ll remind you of Beetlejuice,” Allison quipped.

Allison stayed on the mend and in the championship hunt that season, tough to the end.

Sometimes when Robbie Allison goes golfing, or perhaps just when he’s missing his father, he’ll break out 1980s-style golf shoes to wear when he hits the links.

They are Davey Allison’s old golf shoes, still kept and maintained 25 years later.

They fit Robbie perfectly.

“I love that we have his stuff,” Robbie Allison says at his mother Liz’s home in Nashville, Tennessee. “Some of it means more to me than others, especially the things that we have in common like his golf shoes. Those fit me perfectly. … Those tangible things that you can wear and see and feel, those mean more to me than anything else.”

The shoes are a tiny part to the many items the Allison family has kept over the years as a way to honor and treasure Davey’s memory and legacy following his tragic death after a helicopter crash in 1993.

The Allison collection of Davey’s possessions has grown over time, swelling with fresh material thanks to the outpouring of support from fans.

Over the years, Liz Allison, Davey’s widow, says fans will send pictures, clothing and more.

“I still get pictures,” Liz says. “People send me pictures still. Like they’ll come across, maybe they’re cleaning out their garage or something and they’ll find stuff. I actually had somebody send me a message recently and said, ‘Hey, I have an autographed hat that I’d like for the kids to have in the collection.’

“We so appreciate that people have kept all this stuff through the years, and that they would share it with us.”

A family favorite is something Robbie wears when the weather gets cooler. It’s a sweater, “clearly from the ‘80s” he says, with Bobby Allison’s 1988 Buick Regal on the front, styled in a classic 80s way that makes it almost look like graffiti.

It’s a compliment-getter whenever he wears it.

“It’s one of those things that you could wear it now and it would look like somebody had made it this year,” Robbie says. “I swear, I only get compliments from people that are like 25 and under. And they’re like, ‘Dude, that is sick, where did you get that?’ ”

Wearing that sweater, or the golf shoes, or perhaps using Davey’s old fishing rods or bows brings a sense of proximity to his father that Robbie otherwise might not experience.

He was not yet 2 years old when his father died, yet his favorite hobbies are exactly the same as his dad’s. That he can enjoy them while using his dad’s gear creates a bond between the two, even though Davey no longer is here.

“I love that we have those things in common,” Robbie says. “I love that we still have those pieces of him intact, and that we can hold onto those and I can pass those on to my kids, and it can be part of our family forever.”
