National parks in the U.S. will sharply drop the number of days they allow visitors to get in for free. After waiving fees 16 days in 2016 and 10 days in 2017, the @nationalparkservice announced that it will have four no-cost days next year: MLK Jr. Day (Jan. 15), the first day of National Park Week (April 21), National Public Lands Day (Sept. 22) and Veterans Day (Nov. 11). The Park Service charges weekly entrance fees of $25 or $30 per vehicle at 118 of the 417 national parks. They have proposed raising the cost to $70 at 17 busy parks mainly in the West, including @grandcanyonnps and @yosemitenps. Thanks to Eyewitness @callenalm for this gorgeous Yosemite photo.
