Right, so my theory. I was a 90's raver, and a dopey fucker. I absolutely would have gone off to someone's house at the end of the night, not logically thinking of how to get home from there. Also, when I'm done and I want to get home, I really want to get home. So being told the next bus is 2 hours away, I would try to walk. I think he just went walking, would have been dehydrated from the yokes and dancing, and collapsed up the hills.
