The last few yrs on the Saturday a bunch of the shops in Brownsburg have tours during the day. Dunno if thats on for this year though.

Pit Stop BBQ is right around the corner from most of the shops,and is a cool place to check out with tons of photos etc and an old midget on display there.

Cant remember if Little 500 qualifying is on Thursday or not,but thats something to check into. I went once years ago before I lived here,and it was free to get in as I recall.
