Am I the only one who gets the creeps about intruders when in a tent? Any tips on trip wires (apart from tents own) or alarm bells etc. When with my DH its fine - hes a huge 6'7 but when alone I don't sleep as I'm on constant watch. (had a bad experience at Glastonbury 15 years ago waking up to intruder!) I'm going camping twice this summer with DC alone. Would be nice to relax at night without valium!
