Totally worth arranging a tour (call ahead to arrange). The owner is exactly who you would hope would own it - like a cross between Stevie Knicks and Elvira. Fun ghost stores and info about Tulsa during the prohibition era.
Fun, kitschy little stop. You can climb all over the whale - no swimming though - and take fun pictures - great place for a picnic. Just next to it, you can see what was once the snake pit (now empty!) that was part of the adjacent petting zoo the owners ran decades ago. Cute whale gift shop.
Unfortunately, this has been closed for several years. The area is the Tulsa State Fairgrounds. Some of the equipment from parts of the old rides are on display and at the flea market in west Tulsa.
