What you have
here is quite a clever idea. It's a two drop log flume with a track layout
that takes up only a small and compact area, meaning even a park with
limited space can have a decent flume ride.
I wonder if the same can be done with a rapids ride. I've seen a
travelling one reported on, but not one that comes within nearly a compact
area. Maybe if you got some type of elevator for the boats instead of a
conveyer belt, and a multi level chute of water flowing down in a spiral
with various features.
