I just came across this..
Calling Bob and Joni!
The 'reunion' is being organised by two Germans who have written books about Crete. They are hoping that many "veteran" hippies will respond to the invitation and will travel to Matala for a weekend in June.
Those interested in this "reunion" can contact them via www.arnstrohmeyer.de
I wonder what response this will get from the locals, and do they know?! Actually, I expect it will be good for local hotel and taverna trade - can't see too many people camping in the caves, can you?
