I was in Golden and had lunch with a friend.  We had some time after lunch and walked down toward the river.  As we were approaching the river we heard a lot of cheering and yelling coming from the river.  It seemed like odd timing since it was the middle of the week.  I knew there were ball fields nearby, but it didn’t make sense that there would be a ball game in the middle of the day in the middle of the week.  As we got to the river, we saw a crowd of men standing in the river in one of the eddies.  They were hooting and hollering as they took turns doing belly flops into the river above the small rapid and then swimming to the group of men.  There seemed to be no end to the line of men waiting to belly flop.  There seemed to be no end to the fun they were having.  I cannot say what prompted the belly flop competition or where the men came from.  After we were done with our walk, they were gone as if it never happened.
