We've done two of these marathons this year. We get up early, pack lunches and snacks, and head out. We drive around the countryside looking for caches. Both trips lasted 9-10 hours and we could have kept going but dinner beckoned us home. On our first trip we found 27 caches and on our second we found 22. We're sitting around 470 all-time caches found for us and have the goal of finding our 500th before school starts in a couple of weeks. Another marathon, or maybe two, and we'll reach our goal!

Geocaching is free, although you'll pay for gas driving around. I do encourage you to purchase the geocaching.com app for your phone. It is well worth the few dollars it costs!
