Hey Jeremy,
I would agree with all your "good" items, especially trams, clean porta-potties, great volunteers, and great people overall.
I would add:
THE GOOD:
1. Webcams were Much better this year, very good resolution, lots of coverage.
2. Lot of good vendors
3. Great airshows
THE BAD:
1. Cellphone coverage (AT&T) not so good.
2. EAA WIFI coverage so-so, bandwidth so-so, but somehow the wifi did not allow email retrieval, pop3 email blocked for some reason.
3. We were camped (in "improved camping") next to a vendor area with a big party tent. He felt that everyone in a 100 yard radius wanted to hear his loud music.

Overall, another GREAT Oshkosh!
