This is a really important post. Something I've noticed is that more people climb in the Bay Area than anywhere I've ever been before. I wonder if its at all related to the stress and personalities contained there?
The West is also a great place for climbing (geographically speaking) - far better than many places I've lived... but I'll also vouch for climbing being a great activity. Ultimate Frisbee as well.
It is a trendy hobby. (Nothing wrong with that.) It os socially rewarding to have a popular hobby. Some people run or bike or play basketball.
