I've posted a bit about drastic changes to Big Thunder Trail, but what about subtle ones. How hard would it be to simply add some AA bears or other "frontier" wildlife. Rabbits coming in or out of holes, squirrels possibly a skunk. BTM can be used as the example for this. They call it "Bear Canyon" but the only time you can actually hear the bear growl is when there is no one there.... TURN IT UP... Scare the animals! There is a lot you could put there, make it a 1 hour cycle that way it would be something new besides a fake fish splashing in the water.
