At one of the last bars on the trip, we stopped in and were having a quick drink while chatting with the ladies tour that was friends with Dennis.  One of the guys had been flirting a little with the girls.  We turned our backs and next thing we knew this guy had been hit over the head with a beer bottle and some guy took off.  The victim was out cold and probably suffered a concussion (note the front of his pants).  We decided not to finish our drinks and headed on to the next place before the police showed up to start questioning people.  The guy did regain consciousness before we left but still had some head bleeding as we rolled out on the sleds.
