EUREKA, Mo. (KSDK) - Friday night 216 brave souls will embark on a nine hour rollercoaster marathon at Six Flags.
They'll be divided up into teams of nine and spend the night riding the nine coasters at the park over and over. The team with the most members still standing at the end will be declared the winners and entered in a pool for a shot at a free trip to Washington, D.C.
Other prizes will be awarded as well.
