During the 80's cold spell that was mentioned,I had just reached the Sky after a short walk and stood at the river's edge taking in all the scenery before stepping in. I was wearing the old rubber chest waders and must have stood for a bit too long. When I went to step in to the run, my waders had frozen causing the rubber to "break" where my knee cap is as I stepped in the river. It was a couple feet deep where I stepped in and the 6 inch "break" in my waders filled up pretty darn quick. Shortest fishing trip in my life. I didn't have much money at the time but was at Ted's within an hour to buy a pair of 5mm Bear bootfoot waders . One of my best purchases ever!
