Ah, bicycles, the Peltier devices of transportation. Costly, ineffective,
life-threatening, elitist, snobby. The true believer takes an utterly
impossible situation like snow and turns it into an occasion for truly
wacky make-believism.

Tire chains? Why don't you just invent a bicycle-powered helicopter and fly
over all the weather? More feasible than a bicycle in snow.
