Growing up in Michigan, everybody shoveled. I’ve done one full and one partial shovel so far in the last few days, despite being over 65 and with bad knees and back. It is the law, as webshaf pointed out. The one caution I would make is that the shoveled areas are often more dangerous than the unshoveled spots, especially where the grade is steep. Walking in soft, uncompacted snow is probably safer, as the bare and/or compacted areas quickly ice over. Don’t mean to sound condescending, but there do seem to be a lot of people around here with little or no snow or ice experience. A broken tailbone is no fun!
