Billy,
I'm in Galion. I'm only a month or so into my Arduino Mega 2560, but making great progress with it in my robot. I'm using it to research smart wheelchair technology. You can see it on my blog (www.JohnLizotte.com/robotics). I'm not aware of any groups around here.
If you'd like to share ideas, just pm me here, or use the contact info on my blog pages, and I'll reply back with my email.
