|I could give you a list of reasons why you should Geocache, but instead I'll just tell you that it's the most fun you'll ever have.
All you need is a pen, a smart phone and a free app! I wrote a cute little blog about the process, the different types of caches and which app to download. Check it out: http://www.newbyfunresorts.com/2013/12/geocaching-for-rv-campers.html
I would highly recommend trying it.
If you've already done Geocaching where did you go? Did you find any treasures? Did you leave anything? Where are the best places to cache?
