I've been to a civil boneyard out of Mojave, CA. We landed there coming back from a $100 hamburger trip (actually, it was a $100 omelet) from Kern Valley Airport up by Lake Isabella. We taxied to the hold short of the approach end and shut down, in the event we had to make a quick getaway. Then we went climbing around some of those hulking monsters... trying to sneak our way into the cockpit or cabins of the larger ones, all while keeping a sharp eye out for the owner of the property (rumor has it that he carries a gun with him).
