The Problem is we see it far to often . the camping its self ain't the issue there's another poster near the main road access asking people to take litter home with them . The pile of rubbish after last bank holiday was enough to fill a small skip.
Maybe the National Trust put a couple of tents up, threw some rubbish around and then took this picture.
It might not be a real camp just to make a point.
We once found a wild campsite in the Brecon Beacons which was 100 times worse than that picture above. Stuff was blowing through the woods and small firepits everywhere. And guess what... It was all army ration packs. We took photos and reported it, turned out it was the TA and they were in big trouble.
