Lauren and Steven Keys wanted to see national parks, so they took seven months off from the daily routine and headed out on a 34,000-mile journey that took them through the National Park System. We ask them how they did this, what they saw, and how they afforded it. We also take a look at visiting Joshua Tree National Park, and raise a question of why the National Park Service continues to pursue capital projects when it struggles under a roughly $12 billion maintenance backlog.
