I once read that built into the runway at the WDW airstrip were a series of bumps that would tap out "when you wish upon a star" when you ran over teh bumps in a single axle aircraft. Well last year my wife and I were staying at the Contemporary and I came across the end of the runway when I missed my turn. I drove around the poles that block off cars from entering and drove all the way up the runway to the circle at the end used to taxi a plane. I then drove all the way back and exited the way I came,I videotaped the whole thing and at no time did I ever here anything except evenly spaced thumps. Was that effect ever there or was it just a rumor?I know it would sound different in a double axle car but I didn't here anything.
