My husband and I plan to take a road trip from our hometown in ohio to sedona arizona. We would like to enjoy some stops along the way. We are mid 20s no kids. Like being outdoors mostly or anything unique. We would like to find free or inexpensive things to do. Major cities going through is st louis, tulsa, oklahoma city, amerillo, alberquerque. My main question, is there anything we should stop for both at the major cities or small towns along the way? We have never gone through most of these states before. We plan to go in early october (best time in sedona area) our main time will be spent in arizona but we have several days there and back to see sights. Any ideas would be great, again open to suggestions. Any unique places to eat also would be great.
