#1, no doubt, is the Indy 500. Every racecar driver in the world would like to win that race. Nothing else is even close.

#2, the Four Crown. Even though I terribly miss the old 2 day format, it's still the biggest short track event to me.

#3, Indiana Sprint Week at the 'ol home track, Lawrenceburg Speedway. Even qualifying is a spectacle for this race.

Can't say I have a favorite non open wheel event, so in lieu of that, I'll give you the 2 defunct events I miss most:
#1, the original Border Wars- Eldora and Winchester back to back. Only the brave need apply!

#2, the Copper World Classic. Went 3 times with my Dad when it was IndyCars, Silver Crown, and Midgets at PIR during the day; CRA sprinters at Manzanita on 2 nights. Open wheel heaven!
