Did three consecutive summers at kids camps in the States (Connecticut 2 years, Pennsylvania the other) when at the Poly.
Money wasn't much, but then again I had free flights, free food and board for 10 weeks, fantastic weather, great activities, a couple of shags and good memories 20 years on!
All I had to do was look after 6 brats all day!
EDIT The shags and looking after the kids were not connected. Just saying....
