What songs did you sing, ranger1? Not mournful ones, I hope? I love people to sing happy songs as they work.

One time I stopped to rest on a mountain trail. Down below me, many zig zags back, I heard someone singing a song in full voice. Sounded pretty good, so I waited until he and his companion hove into view and then I said, Good song! He said, Just keeping the bears away- and broke back into song as they passed on by.
