My husband and I have 3 weeks in America (last week in September and first 2 weeks in October)and are thinking of driving from Vegas to New York. My husband has multiple sclerosis and uses a wheelchair so we can't do hikes or anything but we love scenery, wildlife etc. Can anyone suggest any routes or advice? We dont have a 'to do' or a 'must go to' list so are open to all suggestions! We thought we would spend about 3 days in Vegas and 4 in New York.
