People we spoke with acknowledged that many residents are vets suffering PTSD, criminals on the lam, meth heads, and others that prefer to be left alone. But that some members of the community have built infrastructure for tourism, and it’s tolerated.
People considering visiting Slab City: just bring a warm heart and open mind, it’s really not scary or dangerous to go as a tourist. (Edit: also bring your street smarts of course, just like when visiting Union Square in SF)
I'm not a negative person, but I have to rebut your comment that it's not dangerous. I've been homeless and lived among homeless. It's not unusual to send someone out to befriend people of your type while the rest figure out the best way to rip off everything you own.
