On our dog walk today, we tried to find a geocache in the woods. I had downloaded an app for my phone and it worked pretty well for the first one. (not so much for the second one we tried to find though) We searched and searched and it said we were within one foot. Nothing but some logs. Then, Duke said, "There are words on that log". Aha! He found it. It was a log with a bit hollowed out and a tiny bottle in it with the register. So fun! The kids loved it - we will be finding more in the future for sure!
