Thank you Kearnyirish2.
I’ve never heard of geocaching before your post.
You’re welcome; it’s a lot of fun, and a good way to get the kids outside while learning about some nearby places you might not have known about. I’ve seen a trend where the containers (sometimes waterproof ammunition boxes) are marked with all kinds of notices on the outside so as not to be mistaken for “suspicious packages”. In theory they’re not supposed to be hidden anywhere you’d have to trespass to get them.
