Colorado’s vast, wrinkled topography is full of parks, resorts, hot springs, ranches, trails, rivers, restaurants and historic hotels. When you’re on the go, it helps to have a physical guidebook in your hands — especially since those same mountains and canyons often block cell coverage. Admittedly, I’m a fan of printed guidebooks — so much so that I’ve even penned a few myself, including guidebooks to Nicaragua, Belize and, most recently, “Moon Camping Colorado.” So I was glad to have the chance to talk with Terri Cook, author of the ninth edition of “Moon Colorado,” which came out earlier this year, about what’s new in our state. Cook is a travel and science writer who has spent a dozen years exploring Colorado but still feels like she’s barely scratched the surface.
