Not sure whether anyone would know, but some people definitely would care. Here's
an earlier discussion that you might find interesting. Also a list of all
camping options along the trail - campgrounds, city parks that allow camping, and some businesses that will let you pitch a tent "out in back". One other inexpensive option ($5/night) is the
hostel in Tebbetts. Finally, a little more expensive than camping but cheaper than B&Bs are motels, which you'll find in St Charles, Jeff City/Holts Summit, Columbia (9 miles up a side trail), Boonville, Sedalia, & Clinton.
Good luck & have fun!
