Bob Wheeler, left, president and CEO of Airstream Inc., Jackson Center, Ohio, welcomes U.S. Secretary of the Interior Ken Salazar, who visited Ohio’s Cuyahoga Valley National Park Tuesday to announce several “fee-free weekends” this summer at national parks. Airstream provided a travel trailer to be on site for the announcement. The initiative is designed to stimulate visits to national parks, which boost economic activity in communities surrounding parks. “Outdoor recreation is vital to local businesses and to ancillary industries like ours,” said Wheeler. “National parks and access to camping destinations are important to our customers.” The announcement generated more than 500 press stories, according to a Google search by the American Recreation Coalition which provided this photo to RVBusiness. The “fee-free weekends” are valid nationwide at any park that charges an entrance fee. Of the nation’s 391 national parks, 147 of them charge an entrance fee, ranging from $3 to $25. The admission-free weekends are: June 20-21 (Father’s Day Weekend), July 18-19 and Aug. 15-16.
