But to where? What part of Wittman Field?

Pick a spot. It doesn't have to cover the whole field.

WiFi will get you about a 300 ft
radius, maybe a bit more if you get fancy with the antennas. You then have
to deploy an infrastructure to which you can connect the access points. It
takes money, and all for 1 week's worth? Maybe 2 if you count exhibitors,
volunteers, etc.

I don't think the infrastructure is *so* expensive just to provide a hot spot,
if you don't try to cover the whole airfield. The local coffehouse can afford it.
