My husband and I are planning a trip from New York to the West this summer with our children (12, 8, 5 year old girls). We will be leaving from NYC and want to visit California, New Mexico, Arizona, Wyoming,and South Dakota as well as any other worthwhile sites. Our thought is to drive (we have 6 weeks) so any suggestions on best route, best sites, etc. are greatly appreciated. Look forward to hearing from the experts.
