Boston, Massachusetts is made up of different kinds of sidewalk textures that a wheelchair traveler should be aware of. When going around Boston with a wheelchair, some pathways are more easily traveled on while others are not maintained and could be a nuisance and slow one down.
For example, there could be a smoothed cemented walkway between cobble stones, brick that may or may not have sections that have risen up, slow-lying cobble stone tiles, or newly-laid asphalt. Sometimes there might be a crack or the sidewalk will get narrow. Other times there is access on one side but not at another. We should always be aware of our surroundings and this includes debris or holes in our path. No one wants to slip and take a dive out into a crowd or street.
