Mustang Club Member???

Everytime I drive the II, some Mustang club dude tries to recruit me. I have not joined any of them so far. Some sound interesting: track day's and drag racing, others don't: car shows, matching lawn chairs and stuffed toddlers. Do you guys have any thoughts or experiances on joining a Mustang club?
 
I like it. Being the only one with a II has many benefits. Also you learn about great shops that do work you were planning on getting done or never thought of. It's just cool to meet people who love cars.
