Actually, in Boston bikers don't share the sidewalks at all. In keeping with Mass law and local ordinance, cyclists are not allowed to ride on sidewalks in the City of Boston (BTD Art. 6 Sec. 18). And under Mass law, even if the cyclist were legally allowed (under MGL Ch. 85 Sec. 11B--cities may, at their discretion, allow cycling outside the central business district), they must yield at all times to pedestrians.

It sounds like you have nothing but problems with your illegal sidewalk riding. Perhaps you should think about getting in the street where you belong. It's actually safer. Here's a short little pamphlet that will tell you what you need to know about safely riding in traffic: http://www.bikexprt.com/streetsmarts/usa/index.htm
