Hi Adam
I'm in Almeria, Spain.
Obviously it would be a blast if you came here, but I understand if the place is too small to bother. I could hook you up with a nice space and some audience in an alternative place in a nice part of the city of Almeria, if the facilitator there likes it, if he don't it's explained below why...
In actuality, I would almost recommend NOT coming to Spain, for three obvious reasons.
#1 There is virtually no freedom movement here, that I know of anyway, which is why my freedom-work is on-line and more international in scope. It could be seen a good reason of course, to promote voluntaryism where there is none, but I predict empty seats.
#2 Virtually NO ONE here speaks English. Seriously. My stepbrother went all around the world, and had never had such issues getting around on English as when he came here to visit. -_-
#3 Saying anything critical about government in any public kind of setting normally gets you fines of thousands of Euros. Not that Americans need to bother to pay, but I have no idea what the thugs here can do "legally". But we know you got cohones grandes.
Having said that, you would be most welcome!
I see that you have not included Scandinavia at all, but I know Sweden has a good bunch of ancaps and voluntaryists, especially in Gothemburg and Stockholm, including some good podcasts. (See the group Ankeborg on facebook, you can write in English there, I'm sure they would help set you up with spaces etc.)
Scandinavians speak very good English over the board, so there is not much need for translations. I would basically ditch the peninsula for the Nordics.
Just my 2 cents...
Cheers
