Your best bet is to try to have small, mini meetups locally. Several members have tried to organize more wide-spread meetups in the past and all resulted in chaos, none resulted in an actual meetup. It's impossible to find one location to make everyone happy. Then you have to know how many are coming so you can find a suitable spot for it. Are there costs involved in finding a meeting place? What if people back out at the last minute due to the expense of traveling (very common). Tons of pitfalls.
However, small mini-meetups have been sucessful. Maybe see who all lives in a certain region within one state, for example, then go from there
