I passed what I would call a "left lane parker" at about 5:45 am last week on I-465. He was a lone motorcyclist. Looked to be a Harley. As I approached I could see a skid lid (not full-faced helmet), and LONG pony tail. As I PASSED, I looked over and this guy had one of these on...kinda freaked me out. I just wish he'd put some eyes in that skeleton/skull so he could 'keep right unless passing.'
