This photo was taken a couple of years ago, before the safety fencing was added to the upper outdoor section of track. The meandering downhill vine-path used to provide a visual thrill, as the caterpillar cars would seem to be heading right off the edge of the track before turning in another direction. It was like a gentle wild-mouse ride.
The dark ride portions are still great, but the safety fence has muted the visual fun of the outdoor descent. The good news: the outdoor track's about to get a major overhaul including a new, permanent re-work of the fencing. Hopefully, the new look will blend the fence more naturally into the whimsical setting and bring more fun back to the outdoor track.
