Grafham Water is a reservoir and nature reserve thingy where they do sailing and windsurfing and stuff. The BHC region use it as a rendezvous because it has a large car park and a caff that does reasonable brekkies, but apart from that nobody actually lives there.
Closest is probably Monty who lives about 5 mins away
No matter - just had a chat to a Ducati salesman that says there's a guy from Grafham interested in the same bike I phoned up about - for exactly the same reason!
