IIRC the cost is either free to SCCA members, or Reno Region paid for some of us to go last year.
I'm not sure who's organizing the event for Reno this year, but I'll bet Dean or Debbie know about it... or maybe even Matt since he went to the last RenoSCCA meeting.
The event is cool, but can also be boring. The classroom part of it is pretty dry... I remember Matt falling asleep and knocking over his glass iced tea bottle and scaring himself awake.
The actual "training" is pretty fun, but long. We broke into groups around their mock track and delt with several incidents, like a car off course that needs a tow, or a racing wreck response, and the final scenario was putting out a car fire.
The wierd thing about the event is that it's not really structured for beginners to learn. It's more of a refresher deal for those people who are going to be working events in the coming season. In fact, there really is no way for beginners to learn Flagging and Communications... essentially, you show up at the event to help, and they stick you with someone that's experienced and you learn by doing. This "training" is essentially that, minus the actual race, you just hop in a group and learn by trying it. Just keep in mind that you will only get out of it what you put into it... so if you go, make sure to take the flags at a corner, or take the radio at a corner, and give it a whirl. You'll probably screw something up, but that's how you learn.
