GOOD:

Great to be back.
Food service definitely seems to continue to improve in quality and diversity.
Vehicle-free areas much better enforced this year.
SOS brothers ran a very efficient food/beer service operation and had neat shirts this year.
Some new stuff in the airshow (loved the Blimp acro).
Very good housekeeping service on the yellow shower trailers, lots of hot water.

BAD:

The WIFI and ATT cell data was awful.
The Airventure app sucks when you can't connect to the internet (jeez, all that downloading and it doesn't have offline storage?).
Idiots who bring dogs to airshows and fireworks displays.
More accidents than usual on the runway it would seem.
All the food service shutdown very early (4PM? or earlier) on Wednesday.
Still too many vehicles around the exhibit halls during the middle of the day.
Someone needs to smack the PA announcer and tell him to not talk if he doesn't know something. Blimps are dirigibles. Semi-rigid airships are dirigibles.
Too many personal conveyances in the crowd areas.
Insufficient portapotties in the Vintage area (including keeping a good number of them locked up more all of the preshow).

UGLY:
New tram system is a disaster. None of the previous problems were addressed and it got worse:
1. Missing and inadequate signage.
2. Insufficient stops on the blue tram.
3. Yellow tram is silly short with too many stops.
Insurrection that happened in the parking lot exit lines necessitating Oshkosh police response.
Idiots who decided to pass other airplanes on the taxiway in the departure conga line for no apparent reasons.
Idiot pilots who drive their Cessna 310 through the crowd contrary to instructions/ marshalling to obtain a "perfect space" that nobody else was using.
