One of the aspects of Moto America motorcycle racing at Road America is "touring" during the lunch hour. Citizens, for a fee, are able to ride their personal bikes around the vaunted 4.048 mile track for about 30 minutes.
Here, a few of the participants are heading under the Johnsonville Bridge right behind 4 moto-officers from the Wisconsin State Patrol who joined in the parade with lights flashing....but no sirens.
In addition, the bikes were spaced out among 3 of the track's pace cars so the testosterone of the riders doesn't overrule their brains. Yes....of course they have to sign a hold-harmless waiver before being allowed on track. The last thing the track needs is a lawsuit.
Large is best.
