As for how much do they own, I don’t remember the exact number, but it was large. I have walked from the Church down the hill to the lake and SDC owns all of that. That space would be ample for expansion, but I have never heard them talk about expanding in this area (This would affect the Cave). I have heard expanding between Powder Keg and Wildfire. At one time they said they wanted to have that area be the “Thrill Ride” section of the park. I have even heard them talk about removing Echo Hollow like I had said in a different post. There is a lot of good land in that section that is not used. I agree with Steve, it wouldn’t be wise to remove there largest venue, so this would probably mean they would build a new one in a different area, but where?
Hmmm, I kind of hope they aren't still holding to the idea of keeping all the thrill rides in one place. There is something to be said about keeping rides from overgrowing into SDC's atmosphere too much, but as we saw with TGS, there are better ways to do that than keeping them all bunched in a corner.
Echo Hollow is over 25 years old now, and though it holds around 4,000, I'm sure it's not as well equipped as a new amphitheater could be. I wouldn't be surprised if they have plans to use one of the valleys for a new, larger one soon. Even if they did though, Echo Hollow would still very valuable as it would still be useful for a lot of major productions. So, I really can't see it going anytime soon.
Say, does anyone have a map or something that shows where Marvel Cave really is? I mean, does it really stretch all the way down the valley? Does Wildfire go over part of it?
