When Keith Combs and I arrived in the small town of King Salmon, Alaska last summer, we had an afternoon to see the sights of the town. It didn’t take long. In fact, our hostess, who’d been raised there, told us that when she’d left King Salmon to attend college out of state her classmates had teased her because she didn’t know the difference between a green light and a green left turn arrow. Up until then, she hadn’t needed to know such a thing.
