If you are looking to learn more about the National Parks when you visit, you may want to attend one of the Association or Institute classes. I was scrolling through some of the new classes and hikes today and they look amazing! Here are links to The Yellowstone Association, The Yosemite Conservancy, The Glacier Institute, The Zion Association, and The Grand Canyon Association. Check out their classes and talks and let me know about any other park classes you see. Craig and I are going to be keeping an eye on their job pages as well. I would love to work in one of the park bookstores or as a guide.
