Powerful moments at the Daytona 500 with Denny Hamlin winning for Joe Gibbs Racing (Joe lost his son JD recently). So why did the trophy wind up with Joe at a Steak and Shake? Here's the coach explaining the meaning:

When we won the #Daytona500 in 1993, we didn't know what to do, so we took the trophy to @SteaknShake near the track to celebrate. Tonight we continued that tradition! @dennyhamlin even showed up. #NASCAR #TeamToyota @FedEx https://t.co/qa43If07Qk
