I peer down through the darkness to the coastline sketched below. Tiny towns and broccoli-sized trees remind me of a scene from a puzzle, huddled together along the shoreline of one of the Great Lakes. It's July 2nd and we're flying east towards Massachusetts to celebrate the Fourth of July with family in Cape Cod. The sun is just starting to set from our vantage point above the clouds but the families below us, already in shadow, are shifting into night mode, chasing fireflies and lighting bonfires.
