Don't think these have been posted here, but here are the mist, water effects, and general consumables that B S T added for the rapids, taken from some interesting angles around the ride
Inside the tunnel, (originally built by Space Leisure) showing the new misters that B S T added, interestingly using hydraulic nozzles to generate the mist using high pressure water, instead of using the conventional water absorbing chemical based misters
The back of the old pumping station building
The pnumatic driven water shots they added, testing below . Those levers haven't moved for a long time.
The old mining company building, (originally built by Space leisure) after it had been turned in to a boat. The original building influenced the new Gold Rush coaster, and had a sign with a very similar appearance to the Gold Rush sign/logo.
It would be good to see further effects added throughout the rapids area.
