Psych, it's in Lynn.1
Massachusetts is fired.
Anyway, I'm probably going to ride out to one of those on Saturday, starting when I'm back from Tai Chi (11 or so). It's supposed to be sunny and 40°, which is like summer. I figured I'd go with the one with the little shed where that dude lived that one time and they tore down the shed and build a new one just like it. Anybody feeling particularly Thoreauvian, you know where to find me.
1There is a Walden Pond in Lynn. I'm sure it's a nice pond. It's not Walden Pond, though. But if you start in Medford and just say Walden Pond, guess where Google Maps wants to send you?
