Reminds me of the day I decided to clear off the pond out back so I could make an ice rink. It had been -20 for a while so I fugured there would be good ice coverage. I drove the old Oliver tractor onto it and it made short work of the job. That was, until I got into the corner, where all the dead leaves and minnows had started to ferment. Once the first wheel goes through, it is just a matter of time until you have to abandon ship. By the time I left the tractor, just the top 1/4 of the back wheels were showing.
Then the real trick comes in trying to winch it free before it freezes in and has to wait for spring. In spring the pond doubles in size, so there would be a lot more damage. My recovery training (I was a mechanic in the military) came in handy that day.
I've moved since then and sure do miss that old pond. It made for a nice shooting range. Nearest house was a mile away in any direction, and even those were far and few between. Lots of wildlife too, but not being a hunter myself, the only creatures I ever dispatched were racoons, for the offense of constantly eating all the cat's food. I still have a cat dish with 9mm holes in it from where I would miss the furry buggers.
