We just started!! I first heard about this a while ago and thought it would be a perfect activity for the family. My DH loves techie gadgets and I love maps. I finally got my GPS about 2 weeks ago. We have many near our house. We've gone out twice now, but have only found 1. Well, one was a 4-parter and we found the first 3 clues, but not the final cache. We were going to go out yesterday, but DH wasn't feeling well and it's not nice today. I really like it, but sometimes it's frustrating not to find the cache. I think we've looked for 4, so we're 1 for 4--not very good odds.
