So far, the only way convenient way I've found of using the T is to Pahk the Cah at Alewife which is 5 bucks, but I've considered looking into trying to park somewhere else near Alewife, but it seems to be completely unaccessible on foot! Even if I can park somewhere else though, it's still 4 dollars a night, 8 dollars a week... Fortunately, my classes are in the afternoon, so I only ever need to feed meters once.
