Black Market Costing Yellowstone Revenue

A higher fee to visit Yellowstone National Park in Wyoming has created an illegal black market for entrance permits that is costing the park badly needed revenue. With the park's $20 entrance fees twice the price of two years ago, some park visitors are selling nontransferable permits, which are valid for seven days, to other visitors at a reduced rate. Selling or even giving a permit to someone else can bring a fine of up to $100, but rangers usually just require purchase of a new permit, a spokeswoman said. The black market means less money for a park struggling to find revenue to fix a backlog of maintenance and repair projects.
