Great report. We're familiar with 2 of your stops. When our now 35 yr old daughter was an infant we stopped at a RV park on the Current River. The owners were so friendly and helpful that we left our daughter with the owners wife while we canoed down the river. The husband drove down and ferried us back to the campground. Great folks and a beautiful river. Probably something we wouldn't do these days though.
Also the fort is a great stop, especially if you're a history nut like me. I like to imagine the trading between the different cultures.
