The Memorial Day weekend auto-racing triple is back (Monaco, Indy 500, Coke 600)

Larson should leave Indianapolis if it gets delayed to long. He has a chance to win a championship in NASCAR but no chance in Indy racing.
Couple of things, he leads in the Nascar playoff points by 30 points. Which is a huge margin. He could miss the race and likely would still be in the lead. Even if he didn't, he's already locked in the playoffs, he still has to win in Phoenix to win the Championship.

You only get so many chances to run an Indy 500. He's already qualified top 5 which is the highest ever for a rookie. He can afford to miss the 600. He already has a Nascar Championship anyway. I think he'll be fine if he can't make the 600.
