The Marine Corps is urging mountain bikers to heed the “No
Trespassing on Federal Property” signs
at the east end of the Miramar Air Station.
Military police are patrolling the area, which abuts Mission
Trails Regional Park and Sycamore Canyon Reserve, and they are issuing
citations to violators.
The Marines’ latest warning was issued in response to a
March 16 incident in which civilian mountain bicyclists rode on to a rifle
range while Marines were conducting life firing exercises. An emergency cease
fire was called and no one was injured.
In addition to the danger posed by live firing ranges,
trespassers are also in peril from unexploded ordinance left on the ground
during artillery, tank and mortar training dating back to the 1930s.Even though these ranges are no longer active, many of them have not been fully cleared of explosives and are considered unsafe.
