Tame compared to most on here, but I remember going to Alton Towers and a big boy from another school group came over to where I was eating my picnic lunch, and stole my apple.
And a Guide expedition for our orienteering badge. The whole Company was doing the badge, and this was the final part of it - we were split up into two groups, and sent off to do the course the Guider had set - one lot basically clockwise, the others anticlockwise.
The group I was leading got lost on the open common land. We had map and directions and a compass, but still couldn't work out where we were, where we'd gone wrong, and how to get back to where we should be. Eventually an adult hillwalker who happened past, helped us get back on track.
The group my sister was with got lost too. Where they should have turned, they went straight on, over the shoulder of the hill, and ended up in a tiny hamlet called Bedlam - appropriate!
We all did eventually make it back to the Start/Finish point (the Guider's house) but neither group had done the course properly - and if I recall correctly, the group dsis was with had to be driven back by someone from the village - and so we all failed the badge. The Guider was MOST unimpressed, and we all got a good talking-to!
