Well, nothing other than its fun. I'll be in Camp Scholler all week with my 5-string Dobro picking, talking airplanes and having a great time. Direct message me if you're up for some evening jamming.
EAA-AirVenture is home to 500,000 airplane lovers, 50,000 evening campers, and 10,000 airplanes that fly in every year. It's a city within a city. An American treasure for sure.
