Randy! People ride bikes in downtown Chicago all the time! Cyclists successfully avoid pedestrians in the North 40 and Scholler and everywhere bikes are allowed. You can avoid pedestrians easier on a bike than on a scooter or golf cart or Volkswagen or tram.
I don’t expect EAA will let bikes in most of the showgrounds, but it would be nice if they’d open up more of the roads on the west side (inside the fence) for bicycles.
