St. Louis, MO USA area -- looking for group, club, class, workshop etc.

Looking for group, club, class, workshop etc. in the St. Louis, MO area to help me get started with my 10 year old son.

BensDad,
I'm in St. Peters, Mo. I have an Arduino Uno and am working on a particular project of mine. I'm fairly new to this business as well, but I've managed to get it working...to a degree. I still have some issues that I'd like to overcome with my project, but I'd be happy to show you what I've developed.
