Don't wear pants while walking to the T.
It's perfect. It takes care of everything, plus it provides valuable entertainment for fellow passengers.
Really, it's the best solution to all of the MBTA's problems. All they need to do is install pants-changing booths in the stations, and roll out an ad campaign advising passengers to wait until safely in the station before putting on pants.
HELLO THIS IS DAN GRABAUSKAS. DRYNESS IS OUR NUMBER ONE CONCERN AT THE MBTA. IN ORDER TO PROVIDE THIS FOR OUR PASSENGERS, WE'VE INSTALLED PANTS-CHANGING STATIONS IN MBTA VEHICLES AND STATIONS. THANK YOU FOR RIDING THE MBTA.
Once pantless commuting, uh, takes off, they could charge triple the fare and run trains half as often and not a single person would care. The whole commuting experience could revolve around the donning of pants:
ATTENTION MBTA PASSGENGERS. DUE TO ROUTINE INCOMPETENCE, WE ARE EXPERIENCING DELAYS. FOR THOSE OF YOU WAITING IN AN OUTDOOR STATION, PLEASE CONTINUE TO WAIT ON THE PLATFORM BEFORE PUTTING ON YOUR PANTS. WE APOLOGIZE FOR THE INCONVENIENCE AND THANK YOU FOR RIDING THE MBTA.
I think this is almost ready to present to them. All it needs is a good slogan. Drop trou then drop token--OH WAIT THERE AREN'T ANY ANYMORE. Charlie doesn't wear pants and neither should you? Eh.
