Beagle,
The Summer Camp is a thing of the past more because of the lack of accommodation than cost. Basically, there are almost no Stations left where there is enough space for the studes to stay in the Mess for a month. The last one I was involved in, the groundcrew were not able to be accommodated on camp and we were in a Hotel some miles away at great cost to ourselves. Nothing left over from the rate ones there. We were going to have a Camp last year but the Propellor problem hit at just that time. I think we would have used space cleared by a Squadron being on det. but I'm not sure about that.
