I also would rather see the NNS race still at ORP. The successful turnout at Eldora for the trucks this week looked a lot like ORP used to be when they had the Busch race there. It'd be cool to have the Indy Lights race there on the Saturday night before the 500, too.
And as long as we're shaking things up, I like the sports car series race on the road course at IMS (running today), but it seems odd to have it on NASCAR weekend. It would draw better having it on Indy 500 weekend; they seem to be able to re-configure the infield in time to use both tracks and I'd think more open wheel fans would go. Have that race on Saturday afternoon, the Lights at ORP Saturday Night, then the 500 on Sunday. Sell a ticket package, have shuttles between the tracks, Talladega-style all night party at The Speedway Saturday night.
