You dern kids and all yer fancy new contraptions!
When I was your age I chopped is 8 ft thick both directions because by the time I got to the bottom the top had refrozen
It's contraptions like this that are the reason we don't freeze up on a cool summer day like that "cold" spell you had a couple years ago about shoot the whole country down lol.
Donner, you water line is only 5' deep? Hope there isnt anyone driving over it.
