That is NOT 'Biker Fox' or Paul Tay, T-town's most recognizable nutty bicyclists. No, Tulsa is pleased to announce Mentally Ill Black Dude on a Bike will join that esteemed roster of happy hooligans on Tulsa streets. According to police, the fellow lives somewhere up north and bikes down south just to . . . swerve in and out of traffic at the busiest intersection in three states. If encountered, Tulsans should avoid confrontation and call the police.
