The mysterious stranger with the plow came around again, but although our front gate was wide open, he didn't continue inside; he just plowed up to the gate and stopped.
I went out briefly today to measure the depth of the snow drifts. There's a massive drift running more or less down the length of the driveway, about 30 feet wide and nearly 200 feet long. When I started climbing into it, it only measured about 24 inches deep and the snow was pretty firm about half way down, so it was fairly easy to cross. But I forgot the ground slopes downwards on the other side of the drive, so about half way across it started getting deeper and softer. When the snow swallowed my yardstick, I knew I was in trouble. I had to lay down in the snow and scoot my way across. By the time I managed to make it back into the house, I was soaking wet and exhausted.
Looks like the Ratmobile will stay in drydock for a few more weeks, at least.
I hope the whole winter isn't like this.
