I ran across a old photo of myself today. This was taken in about 1967.
Did you ever see a person growing out of the wall of a cave? Here I am at age 20, in Ram's Horn Cave, just outside of White Sulphur Springs, Montana. A group of us were doing some amateur spelunking in Montana's 3rd largest cave. It's not a tourist cave. It was about a half mile walk from the highway through open pastureland up on a hillside. You could walk 10 feet away and never see it, but we had a person who'd been there and knew how to find it.
