In honor of Veterans Day, national parks will not be charging any entrance fees on Nov. 11.

It's one of several fee-free days the park system has offered this year.

Some outfitters, shops and lodges based in the national parks offer two-for-one deals and other discounts in conjunction with the fee-free program; details at http://www.parkpartners.org/Special-Offers-for-2010.html.

If you're planning ahead to next year, fee-free days in 2011 will include April 16-24, Sept. 24 and Nov. 11.

The fee waiver applies to more than 100 parks that usually charge entrance fees, but there are also several hundred additional national park sites that never charge fees.
