How do you navigate your national park visits?
Are you someone who needs to actually experience the tactility of a printed and bound guidebook, one with pages that can be dog-eared, notated, cluttered with Post-its, and tossed into the backseat when you're done with it? Or are you right at home with a digital guidebook, whether the material is displayed on an iPhone, iPod, iPod touch, Kindle, Sony Reader, or some similar digital media device?
In this day and age, travel material such as lodging pricing, restaurant listings and menus, and shops can be outdated by the time a guidebook is actually printed, while electronic guidebooks can be updated almost on the fly. And yet, digital media can be frustratingly small with screens that tax both your eyes and your patience. And yet, they are so compact it's easy to slip many of them in your pocket or daypack for reference out on the trail. Not that you can't do that with a printed guidebook, but sometimes they're not always the most portable.
So, tell us travelers, printed or digitalized?
