I can tell you at 31 that I'm most likely the youngest member of my club...although I haven't met every club member. I think it is kinda cool actually. These guys were a bit stand offish at first, but who can blame them. Who knows how many one shot wonders had rolled through that club, and bailed after a few months time? I just love learning from these guys, and they will definitely respect you more if you not only ask questions, but heed the advice they give you.
Right now I'm building a 4*60, and every weekend I take the pieces I've finished out to the club so the guys can look it over and offer encouragement or advice.

I guess my point is, yeah the "Old Timers" can be curmudgeons at first, but my experience is that after you demonstrate that you are going to stick around and not be a "flash in the pan" member they really warm up to you. Plus I feel like I have a whole group of "Dads & Grandads" cheering me on as I continue to learn.

Just my $.02
