Well, the nitro regional is a bit of a sore point. I am currently working with two clubs that run nitro trying to figure out the best course of action. I don't want to go into more detail just yet since I'm about to piss someone off. I don't like doing it but it needs to be done.
Keep an eye on the ROAR Region One forum at www.lihobbyinfo.com
RC Tech is a great site but for specific area info it's just too hard to follow.
I'm also planning on going to the Region 2 electric race on the 12th. That's going to piss off the Nitro off road guys since the region one race for them is the same weekend. But I'm an on road racer and racing comes first. Besides I don't know the first thing about nitro off road, I wouldn't be any help.
