Even in that last bastion of marksmanship, the Marine Corps, the heat was on base commanders to shut down ranges wherever possible. One of the ranges on MCB Camp Pendleton (the only 1,000-yard KD range in Southern California) was closed by the base biologist (an anti-gun hippie) because he felt the loud rifle reports would disturb the breeding habits of the California Black Vireos nesting in the nearby willows of Pulgas Creek. Of course, nobody was allowed to point out that the Vireos had been nesting there for 50 years with rifles banging away the whole time, to no ill effect on the birds.
