Thank you to Charles Knight for contributing this image of his dad Jack Knight Sr. teaching actor Ron Hays SCUBA for use in the television show "The Everglades." Charles says in his e-mail to me:

"The attached photo is one of my father teaching actor Ron Hays SCUBA for use in the television show The Everglades. My father Jack Knight Sr. is on the left, Ron is in the center, and the fellow on the right is Bill Cantrell Sr. Whom along with my father and my godfather Arnold (Marine biologist at the Miami Seaquarium) developed the first underwater rescue team in the nation (the guys in helmets on the deck are also members). Jacques Cousteau taught dad and his friends SCUBA in the Tamiami Canal and sold them all the paraphernalia. I recently acquired the photo from a family member. It was taken at the motel pool on SW 8th St. close to 87th Avenue where the railroad tracks cross 8th Street. I seem to recall a lumber store next to it. Please feel free to post it if you like. Thanks Charlie"
