Mazda is hosting a track-related event at Fed Ex field this weekend. 08/12-08-13. Check www.zoomzoomlive.com for details. They'll have a few autocross courses and you'll be able to drive the RX-8, MX-5 & Mazdaspeed 6 at the limits (in second gear).

I went last fall and it was a pretty fun. The lines got pretty bad by mid-morning, but it was well organized. I'd recommend getting there early.

Last year the event was super-lax & everything was hands off. I remember as the instructor walked me to the RX-8 he said "It's not your car, they're not your tires. Let's have some fun". You can guess what happened after that.
