Six Flags St. Louis celebrates the 30th Birthday of the world-famous Screamin' Eagle roller coaster with a 30-Hour Ride-A-Thon on Thursday and Friday, July 20 & 21. Members of the American Coaster Enthusiasts, who consider the classic wooden coasters an "endangered species," travel cross-country to ride the three-quarter mile long wooden coaster beginning at 8 AM July 20 and ending at 2 PM July 21.

Opened in 1976, The Screamin' Eagle was the last creation of famed coaster designer John Allen and said to be his favorite. Standing at 110-feet tall, 3,872-feet long and flying at a maximum speed of 62-mph, the Screamin' Eagle earned the title of "Longest, Tallest, Fastest Roller Coaster in the World" in the Guinness Book of World Records.

This classic figure-eight roller coaster swoops over 11 lifts and 10 lows including an 87 and 100 foot plunge, the two longest drops known at the time of the coaster's opening. Today, the Screamin' Eagle stands in the shadow of The Boss sporting its original red, white and blue colors that it opened with in that bicentennial year. One of the most popular rides at the theme park, the Screamin' Eagle is the opponent that park goers of all ages must conquer before earning their place as a true thrill seeker.
