Men bond over activities. I'm sure many of you have friends for one activity, other for another, etc. It's the rare one that goes deeper than that. What's a good hobby to help you bond with guys you already know and like? It's not so much a matter of meeting new people but solidifying what you have. The barrier of entry should preferably be low monetarily to bring guys in.

Please don't suggest martial arts as my right hand was disfigured in an accident and I cannot ball two fingers fully to make a fist. As far as I know martial arts are a complete no-go because of that for me.
