Wednesday is National Roller Coaster Day, and one local theme park celebrated with some special deals.
Rush Mountain Adventure Park in Keystone was selling their coaster tickets and "play-all-day" wristbands for Buy 1 Get 1 Free on Wednesday.
Owner Tom Hagen says they bought the property ten years ago and initially started with just the Rushmore Cave, but thought they needed a big ride to bring more families to the area.
Rush Mountain Adventure Park and Rushmore Cave Owner Tom Hagen says, "We built the coaster. It was completed last year in September so we just missed Roller Coaster Day last year, but it's 3,600 feet of stainless steel coaster. It goes all the way to the top of the hill, back down 280 feet of vertical relief, such great fun. 31 miles an hour of tight turns, 50 feet in the air. What can you bad about all that?"
The first American roller coaster was invented in 1876 when two men received a U.S. patent for what would eventually be called a wooden roller coaster.
After Labor Day, Adventure Park will offer discounted prices again.
Other theme parks also participate in National Roller Coaster Day, including Six Flags America.
