ah yes I get it. i live a copule miles from the 128 station, so our paths have probably crossed. but I"m not sure why you bother with the train, why not just drive south 95 (reverse commute, we do it to Foxboro and there is never any traffic) and then ride from N. Attleboro or Cumberland?
agree it is cool to see others hop on board. one of my colleages has started commuting 8m RT from Newton to MIT,and another guy bought a bike and done it a few times as well. he is buying a desktop computer now so he won't have to lug the laptop, and move which helped me tremendously!
