The tourist trap at the Caverns were really emphasising the Jessie James angle when we were there. I didn't know back then that the outlaw Jessie had a cousin living in Tennessee who ALSO was named Jessie and one named Frank, so if THEY were into any outlawry, perhaps they were the gang around the Caverns area. I doubt this very much, but you never know.
I went through Combat Engineers School at Ft. Leonard Wood in end months of 1965. I found out exactly WHY it's nicknamed "Little Korea", LOL. If you know someone who is a military retiree, you can get onto the base with them. Then, ask the gate guard for a map of the base. Or, go to the Base Public Relations Office and get one. Ask them which areas are off limits due to explosives training and go from there. There's a really nice river flowing through the base that would make a good canoe trip. We had to do a river "assault" as part of our training, in the middle of the night without making any noise. Heh, Heh. Of course the instructors heard noise the first THREE times.
