. . . that is, the California Conservation Corps. A CCC group was camping near Mike, as evidenced at times by their hooting and hollering during their paddleboard competition. They were putting in full days' work, at altitude, doing heavy-duty trail maintenance. And, they had to hike (miles, in some cases) to their job site carrying large and cumbersome tools.
Somehow, even with their loads as handicaps, they had no trouble catching and passing Mike.
