I actually live in Niles MI, just haven't changed my profile from when I joined. I race at embassy rc raceway. We were closed last year but opening for a limited few races this year. I'm going to try to get to stateline at least once this summer. Probably go to proving grounds a couple of times, and maybe Leisure.
