I can relate to this. I must have a hundred guitar players under my fridge, but those little bastards are fast. As soon as you turn on the lights, it's like they disappear. I'm told they can practically live through a nuke.
On the OP's question: Several ways. We've found people on craigs before, mostly we're old friends... More recently, I've been finding more musical opportunities just by going to local jams and playing with/for people.
