My sister and I were in Portland early this week and we opted for a longer layover - just in case 66 was running late. (which it wasn't). We de-trained in BOS, relaxed a bit, then took the T from BOS to BON (switching to Orange at Downtown Crossing). We had no problems with our luggage, however, it was a bit past rush hour. However, on the way back, we took 680 from POR to BON (arriving around 8am), then took the T to BBY (which was easy, even in rush hour). I think the entire trip took 10 minutes and we had plenty of time before the Acela 2159 came through BBY. Several AU members provided me with detailed instructions, which I had memorized and for some reason
several passengers thought I knew where I was going and followed me.
I made no wrong turns and ended up where I wanted to be.
