Honestly, it's a crap shoot. While the clubs themselves will be thrilled at the idea of your being a member, each individual member is unique.
Most people who meet me think I'm a jerk
but that's only because I tend to keep to myself or hang with my friends. And when people ask me my opinion, I tell them - with complete honesty.
Some of the members are super cool guys. Some of them will be very outgoing. Some will keep to themselves. A magic meeting for some is their weekly social event, so they will want to chat with their buddies. But I guarantee you, that if you are willing to put yourself out there, you will meet some people with whom hopefully you share mutual interests.
And don't worry about not being up to a standard. No matter how badly you think you may suck, I assure you, there are guys there who are worse. MUCH worse.
The IBM meetings try to be more hand's on. The SAM seems to have become more of a "sit and watch" type of club.
If you plan on coming to an IBM meeting, drop me a line and I will try and introduce you around.
I think magic clubs can be a great resource for a magician. The clubs in Lexington and Louisville KY were great for me growing up. Some clubs have issues. I think it can be what you make it.
Give it a shot. You've got nothing to loose.
