Just read a comment you left another about letterboxing. I had never heard of it before, but clicked on the link you provided & now I’m ready to start! I have a 5 yo that I think would love doing this this summer while out of school. And I found a lot of locations in our area. Thanks so much for the new information. And good luck with geocaching. I think we’ll start with the letterboxing first & maybe move on up later.
