I keep seeing the term "Tribe" thrown around in various threads, but I think people need to remember that this is a great big world we live in that extends well beyond the members of this website.
Just because someone parks their RV or van next to you in the Arizona desert, even if they're inside the RTR boundaries, doesn't mean they're members of CRVL or even knew about the RTR, or cared all that much. They could have been there for any number of reasons.
Given the huge numbers of people attending the various gatherings, it's pretty likely there was some spillover from the other RV events in the area (
have you seen how crowded it is by the big tent??).
It's also likely that some of the RV's were owned by those with YouTube sites they make money off of, and were there simply to support their YT channel and hand out bumper stickers with their name on them. Not "Tribe Members", possibly not forum members, just people doing business.
Others came because they thought it was the next Burning Man; a place to party and have fun, and, even if they saw the "rules", didn't bother reading them.
Lots of people don't.
That area is famous for being an RV mecca this time of year. All you need is an Internet connection and computer or smartphone to do a search and find out about what all is being offered in the area. Heck, I'm sure word-of-mouth is responsible for many of the people who showed up.
I think if you want to have a friendlier time and surround yourself with "Tribe Members", you need to send out a few PM's to your favorite CRVL members / friends, asking them where they plan to camp, and if they mind you parking near them. That way you can be a little more confident that your neighbors will be friendly, respectful folks, and not just some RV'r looking for flat ground.
That's my $0.02
