The only way to have meet is to plan something and make it big. That way, even if people flake, it's not detrimental to the meet. I'd try to get atleast 20 people out. And have a decent intererary. Maybe not times but like, meet up, check out cars, photoshoot, bqq, cruise, etc. And a specific meeting time. I have noticed that westcoast people are far less likely to do a meet though, from what i've seen and heard online.
