Head to loudon this weekend if you want a really good show. 3 days of racing including legends and bandalero cars, vintage and modern sidecars, AMA motards, and LRRS road racing. $25 gets you an infield pass for the weekend (I think a day pass is $15 but not positive on that). Lots of good racing and really great people to hang out and chat with.
If you do show up look for a black trailer behind a sprinter rv near the tower and come say hello. I'll be there with a couple pit buddies and I can introduce you to a good chunk of other racers.
Only one real thing to keep in mind as you wander about though, just about EVERYONE is awesome people and will be more than happy to chat about whatever but when it's time to race, it's time to race and you need to stay out of the way unless specifically asked to help. It's not personal, we just get focused and can't afford to let anyone break our concentration.
