Walking in fresh snow before the snowblower arrives creates inverse footprints

I would call those normal footprints, not inverse footprints. We call both additive and subtractive marks left by feet "footprints."

If you were to step in ink, and then step onto paper, that would create a footprint.

If you were to step in drying concrete, that would also create a footprint.

My dogs always leave footprints paw prints on the sidewalk before I sweep off the snow. They're cute until they freeze into ice and I nearly make a cartoon sound effect as I slip on them lol.

The bane of shoveling

You can tell what neighbors have their shit in a pile. The most dutiful and dedicated among them will make a point to clear the snow before anyone has a chance to drive or walk on it. I had neighbors that would snowblow, then sweep their sidewalk and driveway. Never used a grain of salt. They were dicks, but damn if their driveway wasn't immaculate.

I hate that. Walk in the street.
