OK, so a turkey hangs out in Kendall Square. Big deal — I’ve seen a lot of turkeys in my lifetime. Maybe that’s just because I grew up on a rural Minnesota farm, but that isn’t an explanation for why barely anyone around here seems to know what a turkey is. You see, I walked down the path that leads past Quantum Books into East Cambridge twice a day for over a year. In that time, I saw some pretty strange episodes involving the Kendall Square turkey, affectionately known as Mr. Gobbles. I’ve seen him walking, running, flying, sleeping, munching on grass, and being chased by everyone from obese women to skinny kids.
