A discssion about National Parks can be kind of abstract. But it doesn’t have to be. Part of the intention of National Parks is that we use them. Day hikes. Sightseeing. Camping. Or, walking over 1,000 miles. Alone. To say Cheryl Strayed’s memoir called “Wild” struck a nerve would be the understatement of the year. The best-seller turned major motion picture blew many Americans away. The core of “Wild” is about a journey. One foot in front of the other – literal and otherwise.
