trouble is, smart phones make it 'too easy' for people to venture into places that maybe they shouldn't and pre mobiles probably wouldn't have. To call out the MRT is as easy as ordering a pizza and we saw this at Valley when these devices first became universal over twenty years ago. I once got called out twice in one afternoon for two 'Crib Goch takeaways' when the 'mountaineers' found it a bit too scary! We didn't publicise or censure, just made sure they spent a little longer dangling than was strictly necessary
