on the edge of the high desert. This was as far as you could get from the center of the city and still be within the county. Tract after tract of housing developments spread out in every direction where desert used to be. Lawns replaced tumbleweed. Ninety-minute commutes redefined the limits of community. From the parking lot of the DA’s offices you could see extinct cinder cones rising out of the sand to the north. To the south, the column of smoke from the fire threatening my house climbed thousands of feet into the air, dwarfing the San Gabriels. Outside of a few desert rats and dirt bikers, no one came to the high desert out of choice. You came because it was the last place you could afford, or you came for work.
