For the second time in the last month, someone has purposefully dumped gallons of oil on several corners of Glendora Mountain Road. GMR is a popular destination for Southern California car enthusiasts, motorcyclists, and bicyclists. It also happens to be the local road I drive. The most recent incident happened Sunday, March 8th and this time there might be a lead on who is endangering the lives of anyone who uses GMR. 
Motorcyclist Nick Seth-Smith noticed on Sunday a suspicious Red Chevrolet Suburban, thankfully he had his GoPro running and captured the SUV parked at one of the spots where oil appeared. According to Nick, the oil spills, which were so fresh you could smell the oil. All appeared after the SUV had been past and no other cars were spotted in the area around that time, between 1:00-1:30 PM.

As a result of this CHP and the forest service have closed the road to clean up the spills to prevent accidents and environmental damage. The previous spill is reported to have caused at least two minor accidents. Some in the automotive community have suggested that bicyclists are behind the sabotage, yet no evidence of that has surfaced. 

If you have any information please contact the California Highway Patrol.

According to the LA County Road Closure Site, GMR is still closed check status here
