We did the EAA show a few years ago. Stayed a few nights out in one of the the hay fields. Length was not an issue. Width not much of an issue either. Much more room than some of the music festivals we have been to.
Noise is not much of an issue either. People respect quiet times, even in the 24hr genny area most all were shut off by midnight.
Just hope that it does not rain. Then the lanes between the campers become a mudfest & the entertainment changes from the sky to the ground as you watch people who can't drive dig holes in the muck with their wheels.
