Police said the minor, whose age was not given, was approached at about 3 p.m. on March 12 by the older man, described as in his 60s, in a gold circa 2001 Toyota Corolla - or at least a car that looked like it.
The man asked the minor if he wanted a ride home, but when the boy refused, the man continued to question the boy, asking him if he wanted a ride to Honey Farms, police said.
The man is described as having pale skin, curly grey hair and a puffy grey beard. He was wearing sunglasses and a black-and-white checkered shirt.
The vehicle had a red-lettered license plate, a yellow pine tree hanging from the rear-view mirror, and smelled of cigarettes, police said.
