For the first time since I moved back to Boston over a year ago, I've bought a T pass. I've decided "I enjoy driving" isn't enough of an excuse to gratuitously drive to work day in and day out. I walked to Alewife after work yesterday, planning to go to Harvard Square to buy a T pass... asked the guy at the booth how late they sell them at H^2, and he pointed behind me, at the other booth. Turns out they sell T passes at Alewife, too! (Duh! Should have guessed...) So now it'll be easy for me to get the new one each month, as well!
I really, really should have known that was an option.
