yeah, they have alot going on i guess right now. i wouldnt worry too much about it. they'll get things hooked up with you on the 1st weekend somehow if all else fails. keep trying, be nice and remember, they are volunteers.
Besides, the USCRA is like a 3 sided wheel.Slides along, hits a bump, smooths out again and just keeps going. Absolutely nothing to worry about. Show up with your racer and safety gear and you'll be on the track justa smilin' had havin' fun.
ps don't forget your AMA card and proof of insurance
