The dirt parking area at the Alpine Road intersection with Piers Lane is popular with people hiking trails near The Dish, the radio-telescope antenna on undeveloped Stanford University land that overlooks Interstate 280.
Deputies reported a similar incident involving six vehicles in September 2011. As on that occasion, the raids took place in the morning. The sheriff's report this time shows a timestamp of 9:22 a.m. for the Feb. 10 incidents, and 10:37 a.m. for the Feb. 12 incident.
"That area is being hit constantly," Lt. Larry Schumaker of the Sheriff's Office said. He advised hikers to lock their vehicles, close their windows and not leave valuables in plain sight.
