Hi there...this will be our first AirVenture and we're just wondering about what to do with the lawn chairs we plan on bringing for the afternoon airshow. From what I gather, it's a no-no to put your chairs on the lawn early in the morning so what does everyone do with them? Carry them around all day? I can't imagine doing that in the heat and humidity. We were thinking about leaving them in the car and going back for them in time for the show - is that realistic? We plan to be there by 8/8:30am each morning to get a closer parking lot. Also, are beach umbrellas allowed? For the local airshows we attend, we've always put up a beach umbrella by our chairs for shade and it's never been a problem. Is that ok at AirVenture?
