SS,
It is a beautiful site, situated in a wonderful part of the world.
As well as the hospitality of the hosts at the airfield, the other thing I remember vividly was (and I know this is going to sound totally stupid - but so what) Cornwall from the air looks exactly like you are looking at it on a map. I didn't realise the land is so narrow in places, you certainly don't get that impression when you are driving down the lanes along with 100s of visitors doing 25mph.
