I'm pretty sure this sign honors Bill "Moose" Hensley, one of the guys I worked with in the old days. Moose, as we call him, was a regular at both the train and diving bell in the late 70s and early 80s. He now works in maintenance and operation. God bless him! He is a wonderful man, and was active for several years in the Young Life Christian Program that SDC still participates in.
