No one cares about wild camping. Get out of sight of roads and habitation, arrive late and leave early, don't have a fire and goes without saying no litter. I've done it loads of times in Wales, England and Scotland. You won't have the slightest problem
I got one once but that was just for a chair, even then aren't they hugely expensive.
It's illegal to wild camp in Wales no?
Thanks for the help guys, I think I'm just shocked at train fairs and durations after spending too much time in China. Will just have to suck it up.
