A 21-year-old woman allegedly has been harassed by a man driving a white Chevrolet Lumina.
The reported harassment started July 8 as the woman drove up the Interstate 8 grade toward San Diego for a week-long visit.
"I was taking off up the grade last Sunday and I encountered someone," she said Saturday. "He wasn't letting me pass and he was coming parallel to my car."
The driver of the Lumina four-door sedan continued to tail and allegedly harass the woman all the way to Alpine.
The man didn't make any suggestive overtures to her, she said, but when she sped up and left him behind she could see him, "snap his fingers a couple times."
