You’ll have until October 30, 2018, to use your Groupon.
Here’s a description of Shark Wake Park from the Groupon website:
“Shark Wake Park curates thrilling wakeboarding experiences for beginners and pros alike. Key to its operations is its system of cables and towers. Unlike traditional wakeboarding—which requires a boat to tow adventure-seekers across the water on a wakeboard—Shark Wake Park only requires customers to show up, sign up, and hold on as moving cables pull them into motion.”
I don’t have an expiration on this one, so when the link stops working, the deal’s over.
