jdreed noted that it was expected to be warm this weekend. And while my Sunday is already taken up, Saturday is still open. "Warm this weekend" works out to, according to
the National Weather Service, 71 in Boston and 68 in Fitchburg. Maybe I'll get my act together and make the mad train-bike trip, then; I could take train 1407 leaving North Station at 11:20 and get to Fitchburg at 12:51, and ride around a bit, and come home; the most plausible Saturday return train is 1412 leaving Fitchburg at 5:35, which only has the issue that it's after dark. In fact, the magic Boston gets-dark-at-5 thing is quite a pain doing this at this end of the year. But if official sunset is at 4:45 PM, I still have almost four hours out. Having a better light wouldn't hurt; I wonder if I have time to acquire one.
