10 photos that prove you should stop staring at your computer and go enjoy a National Park for free today

Why are you sitting in front of your computer?

It's August. It's hot. The news is boring, and for today only, admission to all 408 of the National Park Service's parks, historic sites, monuments and seashores are open free to the public.

Today's free admission day, one of nine offered throughout the year, falls on the NPS' 99th birthday. And as part of its attempt to revamp its image before the big centennial, NPS has been calling on Americans to "Find Your Park" -- just like the people (and cat) below who did just that.

Remember, you can't post an amazing picture of you enjoying a National Park to social media if you don't get out there and do it first. So consider calling in sick for the rest of the afternoon, get to your nearest park, and just...take it in. It's easy:

Wrapping up today's #mypubliclandsroadtrip Sunday shares with @utahtravels Bonneville Salt Flats view! Managed by the BLM as an Area of Critical Environmental Concern and Special Recreation Management Area, the Bonneville Salt Flats are a 30,000 acre expanse of hard, white salt crust on the western edge of the Great Salt Lake basin in Utah. "Bonneville" is also on the National Register of Historic Landmarks because of its contribution to land speed racing. The salt flats are about 12 miles long and 5 miles wide with total area coverage of just over 46 square miles. Near the center of the salt, the crust is almost 5 feet thick in places, with the depth tapering off to less than 1 inch as you get to the edges. Total salt crust volume has been estimated at 147 million tons or 99 million cubic yards of salt! The Bonneville Salt Flats are comprised of approximately 90% common table salt. #history #mypubliclands #roadtrip #bucketlist #travel #BLMUtah #Utah #findyourpark #GetOutside #GetOutdoors #beauty #photography #landmark #ACEC #SeeBLM #adventure #explore A photo posted by Bureau of Land Management (@mypubliclands) on Aug 23, 2015 at 5:09pm PDT

This breezy cool creek in the Sawtooth Wilderness provided a much needed break from the bugs and mosquitos. Also made for some nice and cool filtered water! The Sawtooth wilderness was full of awesome mountain creeks and lakes. #rushingwater #ic_adventures #travel #travelstoke #wildernessculture #wearealladventurers #keepitwild #thehikemovement #exploringtheglobe #lifeofadventure #roadtrip #neverstopexploring #ourplanetdaily #theoutbound #rei1440project #stayandwander #briskoutdoors #findyourpark #getoutandexplore
