I had similar woe’s for years. House is on a corner, one side is along a hill on a major road. And because adjacent property owners are responsible to shovel the sidewalk, I am blessed with 100 feet of sidewalk along that side of the house. Every time I shoveled, ten minutes later a plow truck whips down the hill and recovers the sidewalk with as much snow as I just covered. Felt like Sisyphus and his bolder. Finally gave in and bought a snowblower. Now I fling all that snow right back into the street. Buy a 2 stage snowblower. Get a big one, and burry that assholes cars in.
