I'm going to guess it was the late 80's or early 90's when I took a cave tour as a young kid and, the guide went by the name Jimbo. I purchased my picture on the way out of the cave, and I wanted Jimbo to sign it. If I remember correctly, there was an office/common area where Jimbo was working at a desk, and I got to go back there and get his autograph. As a kid, that was very, very cool for me to get to go "behind the scenes" at the City. I've still got that picture and it's one of my favorite SDC mementos.
