Anne is criticizing jaywalking? She's obviously Not From Here.

What kind of illegal crossing behavior do you see there, and at what times of day?

Are you referring to crossing within a crosswalk without a walk signal or when the signal is orange? Or crossing outside of a crosswalk?

I see the occasional blatant crossing when Mass. Ave. has green (most often, roughly between the corner where Gap was and the T stop, and crossing to/from the Middle East corner), but I'd guess it's less than 1% of people who do that. I'm very interested to hear your experience.

(Fun fact: when I see people cross this way and interrupting traffic, more often than appearing earnest or calculating, they appear genuinely indifferent, slightly self-conscious, or strutting.)

mmm ... good point.

Any of the signaled crosswalks. Some are at the major intersections, but there are some designated crosswalks, like right near the bus stop, that have walk/don't walk signals (which offers an admittedly generous walking time).

...something about Cambridge that is awful, sucks, and makes no sense? Knock me over with a mallet.
