 We were in the Marines. I was in the Marines. And you bounce around when you're in the Marines, when you're in the infantry. You're always going to different environments to do different kinds of training. And at some point in time, we went and did mountain warfare training. They're teaching you how to tie knots and climb rocks. And how do you survive? How do you kill something? How do you make a fire? The basic stuff. How do you get by in the mountains?
