Thanks for that. I really don't mind where I camp tbh, I'll be looking to visit as many of the ancient .monuments as possible so won't be setting up a base camp of any sort, wake, pack, onto the next site, and so on. I reckon if I pitch very late and rise early I may just get away with vamping by which ever monument I find myself by. Looking at pics it seems there's enough land for a tent by most of them.
That's the plan anyway, though I still haven't set a date as yet.
