I'm in the early stages of planning a road trip from Central Florida to Cody Wyoming for September. We are a retired couple in our 60's. I'd like to plan a trip of about 5-6 days so that we don't have to kill it each day and can take time to do some sightseeing along the way. I'm tentatively thinking of a route that includes Birmingham, Alabama; Memphis Tennessee (we have friends there); Kansas City; Sioux City; Rapid City SD; Cody Wyoming. What say you fellow travelers? Any thoughts? Suggestions?
