Celebrate "America’s Best Idea" with free admission to all the U.S. national parks from Saturday, April 16 to Sunday, April 22 as part of National Park Week. Over 100 of the parks usually charge entrance fees, but you can also save with parks passes throughout the year. Other free days for 2011 include June 21 for the first day of summer, September 24 for National Public Lands Day, and November 11–13 for Veterans Day weekend.
