Back to the old days of handwarmers filled with lighter fluid, and those lousy sticks that disintegrated into powder after a year in storage. The lighter fluid ones are the bomb. They still make and sell them, and one in each coat pocket can really make a difference out in the duck blind, or ice fishing hole, or waiting for the train up on the platform while the snow is blowing sideways.

I gotta get me some more. I can never seem to keep them around for long.
