Years ago, my brother made a hot tub out of a 3 foot diameter and 5 feet long corrugated steel culvert pipe. He buried it vertically about 4.5 feet deep, and welded a seat inside, although standing in it you were pretty much floating. Solar heated and easy to keep warm!
I have enough trouble remembering a couple of people from a meeting. I can’t imagine remembering a whole mountain of snowflakes!
