Oh ! forgot to mention, back in the decade of 1970, it was a part of hippie culture. Love is always in the air .

Hippies are still exists nowadays. I know about some Hungarian hippies in Tenerife (Canary Islands) and in other parts of Spain. There are probably others too. I am also playing with the thought that I join them. I have contact with some of them on Facebook. Many of them use solar powered electricity and mobile internet. They use as little money as possible.
