Bass Pro in Springfield,MO is the number one attraction in Missouri. They have just opened a new museum called "Wonders of Wildlife" and a new aquarium. This is much raved about worth the trip. I also second the comment about Blanchard caverns near Mountain View AR. There is a Ozark Fold Center state park in Mountain View also well worth the time. If you enjoy folk music, you must visit downtown Mountain View. There will be musicians all around the square in small groups jamming. There is also a pickin' park just off the square where they jam. This is an amazing town. I like the Ozark RV park because it is next to the state park and you can walk to it.
