Scotland is too far for me I'm afraid. Sherburn may be OK if I can find somebody else to share the trip with. There was a PPrune fly-in there a couple of years ago, and it was very good, although quite a lot of people turned back as the weather down south wasn't too good first think in the morning.
Failing that somewhere in the Midlands like Nottingham, Tatenhill, or Leicester (which are the only ones I can think of without a map to hand).
As to the date I'd be happy with sometime in October
