The rockslide at Flooded Mine was a hard thing for maintenance to keep up with, I don't know why. The desk scene was taken out in the mid 70s. I preferred the mine prior to the guns and targets being put in. I liked the animated dummys better. They used to have a few that had a projecter on the face, and it appeared if the "action" was very realistic, but the projectors in the humid conditions had difficulties for maintenance, too.
I was River Rat at the Float Trip in 1979, and I can tell you, it was a fun ride to work at. Gentle, family friendly, and quiet and relaxing. I miss it.
I do like the plunge and the lost river, but I wish they would add more attention to detail and theme and atmosphere things better.
I like the idea of busting a hole in the back wall of FITH and taking the track out on the hills behind it, but it is such a classic ride I don't know how others would feel about that kind of change.
