Shout out to my tribe. I’ve never seen these things before. They distributed these to the tribal “elders,” of whom I am one, a few months ago. I’ve been outside working on the generator getting ready for the next round of ice. Could get up to an inch tonight. We already have had 2 inches of sleet/freezing rain on the ground which had glazed over. The wife reminded me that I had these. They let me get around so well that I even went for a walk.
