Key West is mile zero on Florida’s Highway 1 (U.S. Route 1).
In 1928, it was also point zero for Ernest Hemingway and his pregnant (7-months) wife Pauline. Their Model-A Ford was not ready when they disembarked in Key West from Cuba, a 90-mile ferry crossing. They were going nowhere fast. The car dealer found accommodation for the couple in an attempt to make amends (try that today…).
