I'm not quite sure who you mean by "US". Do you mean citizens of Fort Worth? The City of Fort Worth? Members of the Fort Worth Forum?
I can easily see people in Dallas who are aware of the news releases about this fantasy project lifting their eyebrows, scratching their heads, and laughing at each turn in this bizarre story, much the same as informed people in Fort Worth have. But what have the people, the city, or Forum members done to deserve the same treatment. At the first limited news release that hinted at some sort of entertainment complex I suppose the city was excited, but probably a little confused as to why they had not been in touch with this mystery developer, and the citizens probably thought that some sort of alternative Six Flags was perhaps a viable idea, maybe... But there was skepticism among Forum members from the beginning. Yeah, citizens came out to enjoy the free fireworks but I don't think anyone ever really took the bait all the way, except perhaps a few small investors who are too embarrassed at this point to talk about it. I would guess there have been similar and worse schemes floated in Dallas over the years; life in the big city, you know.
