@Frank Apisa,
Thank you for this advice, Frank.
Try sitting in a tree stand for hours on an icy wet November morning with coveralls and four layers of clothing...you have to climb down about ten minutes before you can't hold it any longer, walk maybe fifty feet away, remove your gloves, and then start trying to locate all the buttons, snaps, and zippers while your fingers are too cold to even grasp a zipper or manipulate a button though a button hole. And then piss into a milk jug. I imagine the deer find it uproariously funny.
Now here's a related story. [I'd advise overly-fastidious people to read no further.] Offshore scallop season is open during the coldest months of the winter. The drags are hauled up an over the stern of the boat and dumped out on the work platform, then they have to be shelled and the scallop muscles removed and thrown into boxes. There's water, mud, and sea scum everywhere and it's cold. The deck hands usually have on a pair of hip boots, and a full set of "oil skins", heavy rubberized overalls and a jacket. Urinating is challenging — stripping off the oil skins (they don't have a fly) isn't practical so the accepted technique is to work your dick free from your trousers and simply piss between the layer of your oilskins and your hip boot. Occasionally cold temperatures combined with great haste result in a misfire — it's not unknown to piss right into your boot.
