Another southern point in Key West

This sign marks the beginning of US Route 1, which goes from Key West to Maine. My particular part of this road is Cityline avenue in Philadelphia and the highway as it turns south through southeastern PA and into Maryland.

I don't imagine that the Department of Transportation normally goes around marking zero on roads since those would normally be state lines. For this one case it is nice that the number line has an origin.

Someday we must get to the othe end of this long road.
