I realised you posted this some time ago Tim, but would be able to include some of your personal content on a blog about Wild Camping I am just updating please?
The blog is - http://www.ecocampuk.co.uk/2015/06/06/wild-camping/
Saw this thread when researching for a blog on wild camping regs etc - which this bushcraftuk is a great source for.
I've got two woodland campsites in Sussex - one of which, Beech Estate located in a 600 acre wood we get lots of bivy, tarp and hammock campers at.
Blackberry wood is nice...
