We love free stuff and you love free stuff, so get excited because we’re giving away some very cool free stuff! National Geographic is hosting the amazing, award winning photographer David Guttenfelder tomorrow and we want to send you there for free. He’ll be talking about his more recent work in Yellowstone, which is as breathtaking and vital as you would imagine. Not to mention, he’s a trailblazer when it comes to smartphone photography, so this should be especially interesting for the social media obsessed among us.
In order to win free tickets, tell us in the comments which national park is your favorite and why.
