We're planning a cross-country trip for next year. We plan to rent an RV. We'll be starting in southern VA. Head west thru the great smokies. Then stops in Nashville, Memphis, and Little Rock. Then we head west to the North Rim of the Grand Canyon for a few days. The bulk of our trip will be UT: Bryce, Zion, Canyonlands, Capitol Reef, and Moab. After that we'll head to Yellow Stone for a couple of days. Then we head home stopping at Mt. Rushmore, Crazy Horse, and the Badlands. We'd also like to hit some Little House spots: De Smet, SD, Walnut Grove, MN, and Pepin, WI. Finally we'll go to Chicago. We're planning at least 3 weeks, possibly 4. Any suggestions?
