I knew they could see me. Families on their way to the lake, truckers hauling loads on deadlines, couples heading for church or breakfast – they all would have found me directly in their line of sight as they screamed into the westbound curve at 70 miles per hour. I imagined that for those 10, maybe 15 seconds, they thought: Is that a person on the shoulder? Where’s his car? What’s he doing? Looking for a ride? Really? Then, whoosh, they were past.
