For some reason there doesn't seem to be one this year. From the plethora of photos that were posted after previous events it was obvious that everyone had a good time.
in fact, I would say "why not this year" ?!
but as Chris said, it could be easier to find someone of the forum accidentally during the day/evening...
or we could be the first to launch this idea, but I will NOT be in Plakias the first two weeks... I think I'll be there from 29 September
