Kyle,
There are several Kingwoods, and which you are returning to is not identified....
If it is Texas, then I may have an idea.
Get the book and take the kids home down the Natchez Trace. Detour for Vicksburg (and maybe the Windsor Ruins - with a TT that might not be fun), but be sure to stop at the Meriwether Lewis memorial and read about a lot of the others stops, you just can't make them all in a summer unless you have all summer.
Antique Archeology has an new store in Nashville, but it would be difficult to get near for a TT and the kiddies will be bored. When we went by, there was a line waiting to get in. We didn't wait.
