Well, maybe we could see a Seaworld further north along the atlantic? Maybe, Sea World Outer Banks, Or Sea World Eastern Shore/Delmarva penninsula
As for the temperatures, they could create a smaller version of the seaworld parks, and contain it indoors, or with a retractable roof, much like ftball stadiums. This way, they can be open year round and have 80-90 degree weather in a controlled environment, as well as shelter from those nasty hurricanes and noreasters...
Possibly a mall of america deal, or a strict aquarium/zoo, with no theme park rides.
Or an entire conservation center/wildlife protection headquarters? They could teach kids about how to deal with certain animals in the wild, especially when wounded, and how they can help protect the environment.
That said, maybe they could do Busch Gardens Asia or Busch Gardens Pacific islands and Australia. They could build it along the pacific, and have great white /whale watching trips.
or busch Gardens Prehistroic Era? A JURASSIC PARK?!?! ok, thats a little far fetched, vbut they are ble to clone woooly mammorths and other ice age animals, accoridng to science, so an ice age park is not far off, but ti would be hella expensive.
