You could contact me at bodhic@racsa.co.cr there are no true communities there, that I am aware of, but we are everywhere as they say, so you never know............What's the deal with the new post coup govt. there I hear it's all pretty much the same less toursim, but it's not comforting for those of us with friends there that there is any kind of conflict.....I have several friends that are in Thailand who may be interested in meeting you.
