On the other hand, the loss of two seaside fairs might cause a gap in the market, allowing for some future businessman to build a new one there one day. It's the circle of life, so to say.
And concerning the Star Jet: Was it earlier raised to the same level as the rest of the park, or did it stand a lot lower than the cut-off pier we see higher up on the beach? It seems weird that the entire coaster dropped four metres straight down in one piece... that is, unless it's still standing on a large slab of pier that simply collapsed vertically. Hard to see what's under the water there.
