Make your T ride slightly more fun with MBTA Bingo. Click the Print button below and take a copy with you. Then just check off items as you see/hear/smell them. And when you win? Yell "BINGO!" as loud as you can - see if you can startle the guy at the other end of the car whose music you can feel in your bones.
