I got hooked last year and ended up taking 2nd in D-Stock Street Tire. I'm trying to make it to every event this year. Definitely the second best way I can think of to spend an afternoon with my wife. Did I mention she started driving this year too (autocross I mean). Anyway, you should really try and make it to the next event at St. Cloud. It's the best track we have, other than the ValleyFair event, which was a fluke. All you really NEED to get started is a car, drivers license and like $35. They have helmets you can borrow if you don't have a SNELL approved one. Other than those few things, you just need a good attitude and a strong ego...cause it sure isn't like driving on the street.
Anyway, Jacob at Morries Mazda got me into it...said it was the best and all, I started going and haven't ever seen him there. Anyway, I love it and look forward to every event. If you do like it, become a member and then register for events online in advance...saves you like $10--$15 per event.
A couple other things to bring if you really want...a cooler with some snacks and beverages (no booze), sunscreen...hot parking lot all day with no shade, some blue painters tape to put numbers on your car...masking tape works too, if you want to be hardcore a tire pressure gauge and air pump/tank.
Anyway I hope you make it.
