WASHINGTON (AP) — The Obama administration says last fall's government shutdown resulted in nearly 8 million fewer visitors to national parks.

That cost the parks and surrounding communities an estimated $414 million in lost visitor spending.

A report released Monday says California, Arizona and three other states lost more than $20 million during the 16-day shutdown.

And the six states that received permission to reopen national parks using state money generated nearly $10 in visitor spending for every dollar spent.
