Howlin Tornado

The signature water slide at the Great Wolf Lodge is called the Howlin' Tornado.
Up to 4 people go on a giant tube down a slide that has a significant
drop before dumping you in the giant funnel shaped area. The raft
travels up and down the sides like a skateboarder on a half-pipe ramp.
Neither of the girls were tall enough to go on the ride but Joe and I
did go on it while the girls watched from below.
