Cold Weather
The human body was not made for cold and wet. Winter fishing and duck hunting are dangerous hobbies. A scary piece on the subject of Off-Season Boating.
Now for a tip on gloves: A fellow hunter was using Maine lobsterman insulated PVC gloves for his decoy work, and they seem like a good idea for any cold wet work. They sell them at New England Marine. Also here. The neoprene uninsulated gloves sold in outfitter catalogues are useless and extremely cold. I am throwing mine away.
