I was in the US last year and I swear I am not making this up. We had gone camping and I had hung my bag on a high branch to keep my Mars bars and snacks away from the bears. I woke up the next morning and to my horror the camp site was littered with wrappings of Mars bars. Bag was in the same place. We never heard anything that night and never knew who ate them but near the camp fire was a foot imprint. It was a really large foot imprint. That same afternoon my friend snapped a photo of some movement in the bush but the thing moved too fast and as a result only a blurry image of this elusive creature remains.
I still get the shivers as I write this.
