Dance Class Is A Dead End?

Salsa classes may not be the best place to meet guys. I can put them in 3 categories:

1. Guys who are socially awkward and cannot get girls to talk to them outside of a classroom setting. Engineers, programmers, "losers," dorks, etc
2. Guys who have a complex of some sort. Napoleon, serious foot fetish, etc
3. Really old guys looking to meet sweet young things

I have talked/danced with guys who I would never talk to/look at outside of a classroom setting. Blech. I think this might be a problem because these guys get their confidence built up way too much.
