At dusk on Sunday, two bicyclists went through the stop sign (failed to stop; didn’t even slow down) at the intersection of Wellesley Road and Swarthmore Avenue. They were going at a fairly high speed, traveling downhill towards town. They didn’t seem to realize that there was a stop sign, or that traffic makes turns from Wellesley onto Swarthmore Avenue. This is a three-way intersection, all-way stop.
