Love the Idea of wild camping. I do it now with my camper van - just find a quiet lay by out of the way to stop over in. Live in fear that some spoilsport landowner will, for no apparent reason move you on. Does my head in that so many car parks have height barriers in that means I can't use them. I suppose it's local councillors protecting their mates who'd like to have your cash to kip overnight on their land.
It was great fun, camped in barns, old cottages, a cave in Betsw y Coed ( spent a week there ).
The fact that you weren't tied to having to be anywhere, meant that you had the freedom to roam and ended up in all these weird and wonderful places.
