If any simple, minimal image could best evoke this place, I'd argue it's this. The monorail opened with the Magic Kingdom back in 1971 and it's been a continuous and distinct part of the experience of being here ever since.
It might also be the most photographed thing on property second to Cinderella Castle. I don't think it's physically possible for me not to reach for my camera when one is passing overhead.
For this, I wanted to capture its movement, so set my shutter speed up to 1/6 seconds and handheld it as steady as I could to keep everything but the vehicle itself clear. Dropped the aperture to f/10 to tamp down the resulting light. ISO settled at 100.
