I agree with you Shane.
I had been to the park at least 20 times before I finally decided to make that right turn and head down there.
When I was there, they handed me a key to the museum and said "Go check it out".
They mentioned that for years it had been left unlocked, but some thief came in one day a took a few things, so they keep it locked.
I wonder if things have changed...that was probably '04 or '05.
Neat place though...they had an urn...storage vessel sort of thing in there that they attribute to the early Spanish Conquistadors. I am pretty sure they specifically think it was from De Soto's party.
