I think that we all wish that we could get the YC sessions, but we actually have a lot of cool people show up to our meetups that you can talk with and learn from. I always have at least 3 or 4 great conversations that I learn from.
We have guys who're working on their 4th and 5th startups. We have guys attend who have exited and are looking for the next go around. We have startup owners that have been in business for several years.
A lot of guys are just starting out on their own, and are interested in feedback on their apps, or whatever they're working on. And, people generally buy pitchers of beer, so if you're broke, you don't have to worry about it. :)
