The $3/gal limit

I set an arbitrary threshold for the price of gas becoming to expensive to drive to work. That price is $3/gallon. Driving home in the snow this am I saw $2.99/gal. The snow will drive it up over $3 easily. I've been prepping. I purchased 700x28c tires & hard mounted fenders. Time to man up & become a full fledged year round bike commuter.
