I read an article about Councilmans Greenfield proposed to law making mandatory shoveling with 4 hours after a snowstorm.
A few people askes about Shabbos
I can tell you the following, When I fell not only was my shabbos ruined. 3 Hatzolahs guys shabbos was interupted (and their familys lunch was ruined) as they came on the call. My entire familys Shabbos was ruined as well.
So you lack of shoveling can affect people who didnt even walk past there
