Or do what I do and get a dog.
I only wild camp these days and a couple of weeks ago I was in my local woods hammock camping with my dog and at 2.30am I was woken by a couple of people walking about 20m away, the dog started growling and because of my covert position between a group of trees well off the beaten track I reached down to grab him to try and stay covert. 2 seconds later I was lying on the floor on top of my four legged friend, tied to the hammock by a poncho I had wrapped around my DD hammock!
Well these guys were obviously deaf, drunk or just wasted as I could still hear them walking on by chatting.
Funny thing is it's easy to get paranoid when alone in the woods at night and I had trouble getting back to sleep after this incident wondering if these guys would reappear later on.
They never did but the local deer were all over the place adding to mine and K9's pointless paranoia!
