Trying to Describe Wave-Riding to a Non-Surfer

Riding a wave is kind of like riding the smoothest roller coaster ever. But, the coaster constantly changes shape. And I get to steer!

Riding waves is arguably the most fun I've ever had in broad daylight. It is more fun than a barrel of monkeys.

I can't imagine ever tiring of riding the waves. How can I have so much fun and live?
