2751Re: Oh Boy, Cold Wars II, winding up!
- Sep 3, 2003I believe that at one time Ed Speer told me that in cold weather
conditions he would take a 4X9' piece of 1 mil thick plastic that
weighed around 3 oz. I recall him mentioning several uses and one of
those was to attach to the outside of his hammock to block heat-
robbing cold wind when needed.
