Locals are for sure friendly to strangers, since many generations grew up with the tourism! What do you mean about safety? We don't expect any terrorist act in the Greek countryside anytime soon! If we decide to go there, we could arrange a meeting, lets say 1st day chill out area, 3pm or something so we'll all meet! Check the psynews album and keep faces in mind! I wouldn't worry about that!
I seriously think to do this fest! It would be nice if we could meet there altogether! Lets do it!
