WATCH: Crazy People Ride Nitro in Shorts and Tank Tops

On Saturday, December 7, the bravest of the brave, or possibly the craziest of the crazy took part in Six Flags Great Adventure's Polar Coaster Challenge.

Riders from 9 different states and Canada filed into Great Adventure to ride Nitro in only summer wear.  There were a total of 348 guests, including the Jersey Shore's Leah and John Emmons of Brick and Jessica Geneski of Bayville. Participating ranged in age from 8 to 65.

Once riders reached a height of 230 feet and a speed of 80 mph, it's estimated the "real feel" temperature was a bone-chilling 17 degrees!

Everyone had fun and the event supported Special Olympics New Jersey as they get ready for their annual Polar Bear Plunge February 22 in Seaside Heights.

Guests also were able to enjoy Holiday in the Park. Six Flags Great Adventure has been transformed into a winter wonderland with more than a million lights, food and holiday entertainment, and of course its world-class thrill rides. Holiday in the Park runs weekends and select days through January 1.
