Each book is designed to be an extremely helpful time savers especially for people who desire to be more tech savvy and educated while adventuring outside.
The purpose is to help money- and time-strapped travelers find the best travel information that best match their interests fast.
They all work the same. Each ebook searches using Presari (my own invention), CalTopo, and the National Park Service.
You bring them up, swipe or scroll to a destination and then click on one of three icons.
From your Kindle, you don't need to read - just swipe or scroll, then click or touch. They deliver search engines, news media, social media, travel and outdoor media - always current, and CalTopo and NPS interactive maps for every destination.
