No, I usually don't park up on the hill anymore. Started liking the pavement a bit too much.
There is absolutely no PDX on May 21st. It just wouldn't make sense to do that before a National event. I actually just got an email from the Mid-Ohio School, and if you're racing that weekend during the OVR National, you can sign up for the Friday evening Twilight Test & Tune at a reduced price of just $150. Just go to the Mid Ohio School website, sign up for the May 21st Twilight Test & Tune and enter the promo code "OVRMay10" to get the reduced price. Plus, and what I've done in the past, you can walk right up on Friday and register right there at the track if you want. Just say the promo code to the lady and you'll even get the reduced price, while getting to wait and see what the weather looks like before commiting to run.
