Happy 100th birthday National Park Service! In celebration of the NPS Centennial, we’re starting the #parkyourhammock campaign! Post a picture of you or your crew enjoying our wonderful National Parks, hammock style, and share the story using the hashtag #parkyourhammock! We’ll share our favorites and our #parkyourhammock winner will get our special edition National Park Foundation hammock! Get out to your favorite park and share the NPS love like an ENOpian!
