You could try Route 66 to Tulsa, 412 to Locust Grove, , north to Jay, OK, then east to Noel, Mo, then over to Highway 13, then North to Springfield. Scenic routes, mostly two lane highway. Not a fast trip, but enjoyable. Lots of things to see. We have taken this route a number of times on our trike. An alternative is continue on 412 through Springdale, Ark to Highway 65 then north. More four lane highway (and short stretch of one of those dreaded toll roads) but still scenic. Good Luck, we are headed to Branson next week to check out campgrounds and relax, to finalize plans for a trip there in May with friends from Colorado who are RV rookies in their new toyhauler 5er.
