New York (CNN) -- An average of $32 million a day in national parks revenue could be shut off if the Beltway showdown results in a government shutdown, officials say. The measure would be the first shutdown in more than 15 years, shuttering national parks, seashores and historic sites, and barring some 800,000 daily visitors, according to David Barna, a spokesman for the National Parks Service. Places such as Yellowstone National Park in Wyoming and Grand Canyon National Park in Arizona would be closed as a result of the impasse. Tourist draws such as the Smithsonian National Museums in Washington would be locked and parades such as the National Cherry Blossom Festival could be called off, though organizers have pledged to hold a short parade despite the outcome. That festival draws roughly 1 million visitors each year.
