No, I can't make it that weekend, but I'll be at the BRG day on June 19 - I highly recommend them - check out group88.ca Drop me an email if you want more details.
First track day on 4 wheels - so you've been to the track on a bike? Man, that takes balls! I hope the 4-wheeled experience lives up to the 2 wheels. From what I've heard, track driving on a bike is a much greater rush than in a car.
UCR is a great way to ease into track driving. You don't get as much actual seat time as you do with other groups, but it's a really low-pressure, confidence-building way to introduce yourself to the track. There's lots of free time for socializing, thinking about your last run, etc. Plus you get to look at tons of great cars while you're there
