If you drive through Bexar County in Texas, take care. Mark Hodgkinson, the "Litter Ranger," may have you in his sights. "I can't stop everybody who throws something out the window of their car," says the burly deputy constable, but don't bet on it. He is the state's only peace officer specifically assigned to cite litterers, and he takes the job seriously. "This is not like being a regular police officer who has a beat, but I try not to think about it," he says. "I like the job and I'll work twice as hard at it because nothing looks worse than going down the road and seeing all this trash all over the place." He drives more than 200 miles a day over the county's 1,248 square miles looking for people who throw items along secluded country roads. And although he packs a 9-millimeter semi-automatic pistol and wears a uniform, some aspects of his image are not totally intimidating. Instead of a traditional black-and-white car with a rack of lights, the 23-year-old Hodgkinson drives a compact yellow sedan with a baby seat in the back for his child. But beware, the compact has a supercharger. And since August, Hodgkinson and several volunteer constables have written more than 200 citations. Out of 75 court cases, he has lost only one.
