Living in the city during this gas craze is fantastic. I take the T everywhere - it's around $40 a month for a pass.
I think I put 7500 miles on my car last year - that's it. Most of the time, it sits parked on the street because a.) I don't need a car everyday where I live and work, b.) finding parking in Boston is like finding gold - once you have a spot, you're very hesitant to leave it, and c.) gas prices are ridiculous.
I feel sorry for everyone that has to drive to work while gas prices skyrocket. Just be thankful that gas is still as cheap as it is compared to, say, the UK. When I was living in London in 2000, it cost about 80 pence per liter. That works out to about 3 pounds per gallon, or (with the conversion rate as of 2000) about $5/gallon. I can't even imagine what it is now!
