If you go through serious snow then 1 shovel is never enough.

I like to have the army style folding and a full size snow shovel. One to break up the ice, or in compact areas, and one to move some serious snow.

If we are going deep into snow country on our 4x4s then having a full size spade shovel is important too.

2-3 shovels per-vehicle when venturing far into snow country as far as shovels are concerned. Shackles, straps, etc, if you have a winch.
