I have been spending time in the outdoors for about 55 years now. In that time I have met some of the nicest people anywhere. Having said that I have frequently bumped into people with room temperature IQ's, people who were rude and inconsiderate and some that were just plain crazy. I never have understood the chain thing anyway when you can get a good drift sock for less than 20 bucks. Or like you said just us a plastic bucket on a rope.
