$1600 is a bit higher but they are offering presales at $1200. OWC is $1000 and Hydrous is $1200 for comparison, so it's not too crazy
I think it's a little bit of supply and demand - how long has CA been craving a cable park? And.. I'm just guessing here... but I bet you this park had a lot more hoops to jump through to get open and proper permitting. Hoops cost money. By the pictures of it the park looks amazing, can't wait to make my way down and check it out.
