We downloaded the free geocaching app a couple weeks ago and haven't stopped since. Who knew local treasure hunts could be so fun? I could not believe there were so many within just a couple miles of our home. If you aren't already using this, I highly suggest trying it out. It's free, and lots of fun for everybody in the family.
Oh, and beware of the magnetic boxes. We were not forewarned of them and likely missed a couple caches because of it.
