I registered on Jan. 11th and put down that I'd be able to help with tech inspections on Wednesday from 10AM until 5PM. I'm not sure if this info. made it to you.
When we attended in 2009, my wife and I helped out and it was fun meeting people, seeing all the rigs and making sure they were all good to go.
Proof of current insurance seemed to be the biggest problem on our shifts.
