Thanks for the detailed reply Jump Complete.
As I currently don't have any of 1) House 2) Job, or 3) Girlfriend (hey, I've just left uni ;-) it sounds like a great time to do something like that. It sounds like what you did was full-time - ie all week on site. Is that right? (not a problem, I just always imagined it being more of a part time, weekend thing).
Is there anything else that PPLs can "get away with" other than glider towing and parachute drops?
