Living in Wyoming we have every right to say we did it first when it comes to our parks. The Cowboy State claims the first National Park and National Monument. In 2016 the National Park Service is celebrating its centennial birthday. This week from April 16th to 24th is a free week. That’s right this week you have free access to any national park. As always make sure you are prepared for the elements. If you are camping or staying in a hotel, make sure you have a reservation.
