With nearly 430 units in the National Park System, of which 63 are National Parks, we all probably could use a little help in planning our adventures into the park system. But do you simply visit a park’s website to plan your trip? Find an online guidebook? Buy a hardcover guidebook? Or simply wing it when you reach your destination? This is Kurt Repanshek, your host at the National Parks Traveler. I must confess, I’ve taken all three approaches, and I’ve even written a guidebook to the parks, and there’s probably a fair amount of guidebook material on the Traveler.  Today we’re reaching out to two writers who make their living writing national park guidebooks. Becky Lomax is the author of “USA National Parks: The Complete Guide to All 63 National Parks” from Moon Travel Guides, as well as her latest titles “Best of Glacier, Banff and Jasper: Make the Most of One to Three Days in the Parks”, which she co-wrote with Andrew Hempstead, and “Glacier National Park: Hiking, Camping, Lakes, and Peaks”. Michael Oswald is the author of “Your Guide to the National Parks”, “National Park Maps: An Atlas of United States National Parks”, and “The Day Hiker’s Guide to the National Parks”.
