Make your MB snow resistant!

I've never had a need for this, and I don't know if it's even possible to buy legitimate snow chains for a bicycle, but this seemed like a quick n' easy mod to give you more friction in snowier climates.  All it is are zip ties that have been placed over the tires and around through the wheels.  I think zip ties are one of man's greatest inventions!  Though since MBs are mostly for recreation, I'm sure this would mostly come in handy in desperate situations.
