Wow, that looks really amazing. It's interesting to hear what they do at different fairs. At our fair this last year, there was a booth where they were making those triangular oriental hats where you could watch how they do it, and selling them. Not a big thing, but I thought it was interesting. I'd never seen that there before. There was also a company that makes pre-fabricated homes (a.k.a. trailers) that had a furnished model home there on site that you could walk through.
Another interesting thing is the types of fair food in different areas. Here, besides normal carnival food, there's seafood, lots of fried alligator, boudin, and smoke trucks selling BBQ ribs.
