I just realized that it's going to be 40 years since Darien Lake became the theme park we know today. Darien Lake started out as a just a campground in 1954. In 1981 Darien Lake got rides and became a theme park.
As for Wahoo Wave, I doubt it will ever open. AFAIK Wahoo Wave is a cancelled attraction like the time that Six Flags had plans for a Justice League meet and greet at park in 2006.
