It's a bit like herding cats. It just depends on the individuals and their needs, frankly.
I joined here about 10 years ago, and apostafests were happening. There was a large one happening in Toronto, and it worked out I could add the stop to a trip I was planning to visit my elderly mother and "elder" brother and family, yeah...that happened. Anyway, it was huge and people came from all over, probably I was the furthest. About 9 months later Mr Flipper arranged the first Tahoe fest, which I went to as well. I am attached to all the people I have met, our world's collided at a time when we needed something, if just to talk with someone else who understood what we were going through. I'm amazed at the new ones that just show up in Tahoe not knowing anybody. Again, there is a need that motivates the effort.
Oh I just remembered I posted on here that I was visiting Tucson about 8 years ago, and several people responded to meet up, and a handful drove from Phoenix, I was very touched. One made it to the restaurant and got cold feet and was ready to walk out, then somebody called to them and they joined....we are friends to this day. A need again.
Based on the society's reports, there are tens of thousands of exJWs everywhere, and the majority just really do want to leave it behind and handle the issues as they come. And it is a painful memory, the former life as a dub, one you don't wish to keep reliving.
So my point...it really depends on timing and the individuals. It's like making friends...sometimes you hit it off with someone, and sometimes you feel like you are on a desert island. It's a numbers game...you never know when someone will see a meetup posting and want to reach out. Seriously, ya just never really know.
But...come to Tahoe! You can camp or stay in a hotel. I promise, you will not be disappointed. Just wonderful people that survived a cult.
