As I was taught by my parochial school parents... "act like you OWN the place"!!!
Meaning... if you see trash on the ground, PICK IT UP and deposit it!!!
If you see where you can help push an airplane or assist someone, DO SO!
Even as clean as the AirVenture grounds are, I would regularly stoop down and pick up paper, popsicle sticks, water bottles, et.al.
I am 70 years old. This was my 43rd Oshkosh! If I can do it, you can do it! I've had a hip replaced and the other one is going. If I am on the ground, I am unlikely to be able to stand up on my own.
This is OUR place! WE ARE EAA! "Act like you OWN the place"!!! WE DO!
