I agree on the LNT principal, but the custodian of the woods I camp in encourages me to build things like that because he uses them and if I'm not mistaken allows a scout leader to use the land to teach so helps both of us out really. The area south of dundonnel mentioned by Steve sounds ideal to be honest because it's a little more odd the beaten track. But there's nothing stopping me taking a few trips and trying out a few places our little group of 3 get out at least once a month and it's just a case of chipping in for diesel
