Your sisters are the ones that are nuts.
I will never have to shovel snow again in my lifetime. The day before the blizzard hit the east coast in Feruary 2003, hubby left for the week for a training class down in Atlanta. I shovelled 33 inches of snow out of the driveway and off the sidewalk and dislocated my shoulder and collarbone in the process. Someone will be PAID before I even consider doing something like that again.
But, now we live in the middle of nowhere, 100 miles south of where we were then so I'm not too concerned. Particularly because I no longer have the stupid city ordinances of how fast you must clear the sidewalks.
Of course I'm saying this as more than an inch of snow has already accumulated outside. and it is still coming down and the temperature keeps dropping.
I hate those laws .. and living in a townhouse is even worse .. The only place to put the stuff is on the 2x4 front lawn ..
One year the snow was so high it was weeks before we could see out the front window again *L*
