Howabout just showing up without your planes and watching? Don't join the club...yet, but hang out and get a feel of what's happening and watch what the other people do.
Here's the tricky part; don't approach anybody, let them come to you. After a while, you might just end up talking to a few people about the planes, and I bet someone will ask you to jion the group. It may not happen at once, but if you keep going and watching, you'll catch on and others will get to know you a little. Hey, it's a start.
Often times that's how many join groups, by showing interest. Others often are more than willing to share their interests with new people. Some even become mentors.
Just think about it. If it feels comfortable, then go slow and give it a try. Really, you have nothing to lose.
By the way, a lot of people think I'm an idiot. After many years of trial and error, I find the best way to deal with that is to remember that I have way more life experience than those morons.
It helps.
