Texas has its Cadillac Ranch in Amarillo—a lineup of nose-diving, half-interred luxury vehicles with psychedelic paint jobs. Near the Natural Bridge in Virginia looms Foamhenge, life-size and realistic but light enough for a druid or two to pick up and realign with the sun and stars as needed. And along a street in Boston, there’s the forty-foot-tall Hood Milk Bottle, a snack bar tucked in along the waterfront. Roadside attractions par excellence, all three are eye-catching, photogenic, and magnificently odd. Odder still by a mile was Miles Mahan’s Half-Acre Hulaville in Hesperia, California, west of Los Angeles, on the road to Las Vegas, the old road.
