MainStreet: "More people are opting to live in neighborhoods where they can walk often, if not daily. Walking is becoming more important as car ownership decreases and becomes less of a priority, especially for younger people, said Stuart Eisenberg, real estate practice leader and partner at BDO USA, the Chicago professional services firm. From 2007 to 2011, the number of cars purchased by people ages 18 to 34 fell almost 30%, according to a study from the AAA Foundation for Traffic Safety."
