Guy,
Great that you are planning ahead for AirVenture! You are very welcome to fly in and you will be able to camp, but just not "under the wing" (er, rotor).

EAA loves helicopters! For safety, helicopters are not mixed with the densely parked fixed-wing aircraft in the General Aviation Camping areas, but the site has dedicated provisions for different rotorcraft types. As noted above, an area near the Ultralight runway accommodates homebuilt rotorcraft. The Warbird area has special provisions for military helicopters. And a few new production helicopters are parked in the main display areas. Since your Long Ranger isn't in those categories, you will use the Transient Helicopter VFR Arrival/Departure procedure listed on page 18 of the NOTAM and park in a dedicated helicopter area on Pioneer Airport. This is a high-visibility and very convenient area close to the EAA Museum, but county regulations prohibit camping there (I guess they don't want you to shower in the Museum). As long as you are an EAA member (you are, aren't you?), you can camp in Camp Scholler. So pack your tent and we'll look forward to seeing you in a couple of months!
