Back in 2010, Nate Henn was killed in a bomb attack that took place in Kampala, Uganda. This devastating loss sent his friend Tyler Dunning down a dark spiral of grief and anger, which he eventually began to pull himself out of by setting a goal to visit all 59 of the U.S. National Parks, where he eventually began to find some solace and healing. This video takes us along with Tyler on that journey, as he learns to say goodbye and embrace the world around him again. This is a powerful and moving short film that is well worth your time. If you watch one Internet view today, make it this one.
