When you are in a wheelchair (which I experience vicariously through my son everyday) a cracked sidewalk is a major obstacle. On more than one occasion, especially in urban areas, we have been forced into the street to make our way to doctor's appointments, restaurants any other places in the community. Lack of funds for maintenance, especially in hard economic times, has created enormous access issues on public sidewalks. Well I am happy to report that in Texas and other places around the country, people with disabilities are filing ADA lawsuits for safe and barrier-free access to public sidewalks. The stakes are high but you should not have to risk your life just to access the community.
