This is a photo from my 2017 trip through Grand Canyon. Dave Edwards is pointing the way. Dave once said to me "if I get quiet, it means you're doing o.k." At one point I hadn't heard from Dave in at least an hour, so I turned around to chat with him and found him sleeping in the back of the raft. I guess I did ok for that last hour?
