I have been tempted to make up signs stapled to stakes that read "wheelchair users not welcome", "mobility aids not welcome", "falling hazard", "pedestrians must use street", "this gas station does not want you to ride the bus", and other snarky comments for all the folks who don't shovel their walks in my area or do the curb cuts. Our city goes through once the night after every storm, so there's no reason not to have the curb cuts done within 48 hours after a storm. [We have a local "no overnight parking" ordinance, which explains why our streets are always plowed reasonably quickly.]
