There was a wreck on the Overseas Highway so our route started back before the beginning, before Key Largo and the big bridge and Little Blackwater Sound. Google Maps kicked us back east, to County Road 905: a long, hot stretch of two-lane cutting plane-straight through swampland. Past Alabama Jack’s, the rickety wooden bar at the edge of the mainland, the only building for miles. Across the small bridge over Barnes Sound and onto North Key Largo and a series of State Parks shrouded in thick, tangled mangroves. A wild, empty stretch of nearly ten miles before you hit Key Largo and reconnect with Highway 1 at the 100 mile marker.
