Charterhall
Only time I ever landed there was as an emergency in 1998 with a blown exhaust in my Europa. I was en-route from Perth to Wombleton in the cruise when the engine suddenly got noisier and I got some extra fumes in the cockpit. Bloke in a 4 x 4 rolled up, relieved me of £20 and deposited me in the nearest village.
The bit of runway I landed on was OK - there was a fence across it which I avoided tangling with. As I recall it's close to the river Tweed. There isn't much to do around there unless you want to go shooting/fishing.
Have you called the owner/operator?
They should be in Lockyear's farmstrip guide.
