Exploring back roads in the mountains can be frustrating. You might spend an hour bouncing down a dirt track, negotiating past washouts and fallen trees, and there is nothing to see but that endless dirt road and trees that all look the same on either side. You’re tired, your whole body hurts from all of the bouncing around, and you start thinking about turning back. Then, up ahead, you see sunlight and a patch of blue sky. You break out into the clear – the whole world is spread out before you – and even the long drive back down the mountain seems worthwhile.
