I still think physical safety is no more a concern than any other place and less so than many. It is a VERY cooperative, chill place. The first time I went I was expecting more craziness (it’s definitely not mainstream, though!) but the vibe is incredibly kind. It’s all about the Bonaroovian code and radiating positivity.

I didn’t mention Brazil because I agree there are unsafe areas, but not the whole country. And, Mexico, well, not S. America. 
The sex trade in Thailand bothers me big time so I have issues with that country (plus the political/economic structure but that’s another thread).
