I'd love to meet up for a weekend in the summer could I suggest a campsite like this: http://www.ukcampsite.co.uk/articles/view.asp?id=4 I'm sure many would be happy to accommodate us if we explained carefully. In particular I know Hole Station Campsite have some awareness of what hangers are like and what we need, they are reasonably hammock friendly.

I'd second having a little sub-group at a BCUK meet up. Bushcraft isn't just about survival nuts - a lot of it's about enjoying the countryside responsibly, leave no trace camping, wildlife watching, etc.
