I’ve lived at this Somerville address for about a year now, and tonight was the first time I recall a helicopter flying so close to the ground. It woke me out of my online stupor, thinking there was some fire or bomb scare nearby. It seemed to be about 50 feet above neighborhood roofs, and I thought it was a MedFlight copter about to land.
I shot some pictures below. The bird appears to have the triangular State Police emblem, but who knows. Weird, though.
