For an event this size, there should be "cart runs" that are separate
from the people.. or separate from non wheeled vehicles. These paths
should be made with minimal disruption of the flow of the show, and
should be on the "back" side of things wherever possible. I know that is
a tad more difficult at OSH due to the layout, but it can be done.. We
are talking about a path that is the wingspan of one plane.. less than
one parking space per row of planes.

The only vehicles that have a reason to go INTO the crowd are medical
and law enforcement. Everyone else should be given a path AROUND the
crowd.

The biggest problem with doing that would not be controlling cart traffic.
It is the people. People walk EVERYWHERE except down the taxiway and Knapp
street, and even then, people still walk down Knapp street, even with a
sidewalk right next to it. Go figure.
