The first part was that I convinced my SO to get out of his crazy 3 hrs per day commute and get a local job. Since he started the new job (accessible by transit or walking), we've barely used the car. He filled up on Sunday and I was looking back to see when the last time was and was blown away to realize it was November 21! Previously, he filled up every 10 days, averaging $121/month in gas alone.
Hooray for no more clown commuting, saving money and reducing fossil fuel consumption.
