A wild tear caught my mind the other day and I started thinking about that almost produced "Disney's America" themepark in Virginia in the 90s. So I googled it, and Wikipedia--far from an objective source, I know--noted that two of the proposed rides from the park; a raft ride a and an old fashioned looking rollercoaster, where eventually arguably put into DCA. Indeed, if you look at the concept art for DA, you can see obvious precursors to Grizzly River Run (although it was originally to be native American themed) and Cali Screaming (visible from an overhead view).
This made me wonder further, if DA had been built, would it gain a lot of the same skepticism that marks DCA (i.e. that it is foolish and arrogant to produce an American themed park for Americans, just as it is arrogant to produce a California themed park for Californians.
Either way, I seriously doubt DA would have done very well somehow--loks too much like early EPCOT, which suffered from an emphasis on education without enough rides.
Here's some of the shots showing similarities to DCA:
Grizzly River Run:
If you look in the upper right you can both see a Cali Screamin' style white coaster, and a farm area kind of like Bountiful Valley Farm:
What do you think? Would such a park have been profitable?
