I find the Basques very interesting. They were a very insular people.
I read a couple of books about Edgar Cayce years ago.
Basques and, dare I say it, I'm fascinated somewhat due to frequent radio caller about the Finno-Urgic types. Kuddos to "Bill from Madison" and I think some other names like Will sometimes. Their is very cool stuff also about indigenous and just random cultures in Russia. The Sami also. And, of course, in SE Asia, Amazon, etc. I like it. Also like weird things about cultures who left to go elsewhere that still survive in a weird way. The Confederates who went to Brazil, white Africans, the whites in various Asians countries, mainly Dutch in many cases. The German colonies in South America. That stayed after colonialism or wars and now are a weird minority.
