Tom and Huck aren't Ozarkian either, nor are diving bells. There have been other proposals, like Lewis and Clark, that also do not pertain to southern Missouri or the Ozarks.
I can see the Mark Twain connection, though...at least it's in the same century as SDC. As the link to the MO Folklore Society shows, the whole MOMO story didn't even really begin until the 1970s. Besides the White River Monster, there is the Ozark Howler and even the Hornet Spook light that might make fun "quests" for a themed ride.
There just so much great local material, thanks to the efforts of Vance Randolph and others, that should be highlighted. If it wasn't for the efforts of Randolph and his friends, I daresay there wouldn't even be a Silver Dollar City.
Again, not trying to be pedantic per se. I'd just like to see SDC return to a little of its roots. There's room for everyone at the dance.
