Emo Phillips once said that some days it's just not worth chewing through the leather straps. I'm sure he was thinking of this guy. While the first incident--finding himself the victim of a hit-and-run--might not have been his fault, the second--getting run off a railroad bridge by a passing train--would definitely find him culpable.
Just another case of trying to beat the train and losing. Hope this guy has better luck in the future.
