Wheeling along the sidewalks of Watertown

I use a wheelchair for my mobility and I currently live in wheelchair accessible housing in Watertown square. I originally thought that it would be “easy” to wheel my own chair down to the square. I was wrong. Even when I tried to stay on the sidewalks that were available, many are too narrow to ALLOW FOR a wheelchair user to use the sidewalk. I know that most citizens of Watertown drive cars, and that there are also some able-bodied pedestrians, but I find that I must use, that I am forced to use the RIDE bus even for short trips due to the narrow, uneven, or even non-existing sidewalk. Trees along the walkway are attractive, but I also must dodge telephone poles as well. I would appreciate any comments on city planning that would allow for better access. Thank you.
