(UNDATED) - The cost of shutting down national parks to surrounding economies is nearing a billion dollars.
According to numbers from the Coalition for National Park Service Retirees, more than 700-thousand people visit national parks on an average October day.
They'd spend about 76-million dollars at the park and at local businesses.
Ten days into the government's shutdown, national parks have lost four-and-a-half-million dollars in entrance and rental fees alone.
In southwestern Indiana, the shutdown has closed the George Rogers Clark National Historical Park, a 24-acre site overlooking the Wabash River in Vincennes.
