The Map That Made Los Angeles Make Sense

For generations in Southern California, the Thomas Guide led drivers through the streets of Los Angeles. Now apps do that. Did something get lost along the way?

Long before I got my driver’s license, the Thomas Guide left a mark on me. Literally: Spread open in the backseat of my dad’s Mitsubishi Galant, the metal binding of its 3,000 pages of Los Angeles street maps would press spirals into my child-sized legs.

I’d flip to a random page, the paper worn and waxy, to peer over some colorful new square. All of L.A. County—5,000 square miles and 88 municipalities—was gridded inside the exhaustive street atlas. Surface streets were a dark blue hash, knots of freeways bright red clovers. Names of neighborhoods miles from our house in the San Fernando Valley beckoned in tiny print: Gardena. Alhambra. Manhattan Beach.
