yeh i used to be in the army cadets,
trust mate i have had 2 experiences at that camp,
torrential rain staying in one of the old station houses train loading bay thingymajigs and theyre not waterproof just because they have a roof make sure you have waterproofs and plenty dry kit
the other time we ended up ditching the buildings and sleeping in the snow under ponchos.
its a good camp with pretty good training area due to the buildings and lake but always cold and wet.
