san diego to ensenada
1930

Long before I-5 in the USA or Route 2 in Mexico the AAA issued a strip map of the route from San Diego to Tijuana. The map is notable not only because of the lack of freeways but also because it shows the mileage in both miles and kilometers. Tijuana on this map was spelled Tia Juana.
