Have a blow torch
My worst nightmare was when living in Calgary, during spring time when cumulated snow/ice over winter melted but could not drain away because drainages were blocked by ice blocks and snow/ice bank by the side of roads and refroozed overnight. You ended up had black icesheet on pavement and road way.
Once I got out of my car but had to hold on to the car to move and the car was more like sliding on road.
Black ice is my nightmare.
It's bad enough on flat land, but on hills and mountains -- insane.
Sorry about the powerlines, but see how perfectly the snow lies on the bottom line?
