Guest Author: The Top Geocaching Apps of 2012
Geocaching is a great way to discover hidden gems right in the wall of your city. It’s also a great excuse to get outside and explore the terrain. A Geocaching challenge is similar to a real-world treasure hunt, where teams or individuals use GPS tracking to locate “caches” or trinkets that contain lists of who has found them as well as details about the find—including notes about the terrain, hiding spot, and trinkets found within the cache.

The GPS signal from the satellite can be adversely affected by:
