Field Day!
I did ARRL Field Day 2010 at the OCRA/DFMA joint field day in Hillsborough, North Carolina, with my parents. The clubs set up a 10-transmitter station, all running at 5W on battery power for the duration of the event.
Sadly these don't give a good sense of the site. Notable innovations are the bucket truck on loan from the power company, and weather balloon; both of which I would describe as solutions to the problem of not having the Green building handy to string antennas from.
You forgot to mention that it was really, really hot.

High of 101 yesterday according to wunderground.
