I had a sergeant that experienced something similar, in PA, I think. He'd gone up there on vacation and been offered the position. His, however, only offered a stipend of $50 a week, and he would have had had to supply his car as well as his gun (they would give him a blue dash light for the car.) This was around 1990.
My dad lived out in the high desert in New Mexico. One of the towns south of him, the town of Mountanair, was along a real bad drug-trade route (probably still is.) That town had a real hard time keeping lawmen, too. I met one of the ones that had tried the gig. Threats against them and their families by drug traffickers usually drove them off.
