niraD, you calmed my fears about the Garmin. I have a smartphone (LG made Alcatel powered by Android)), but I am deaf without hearing aids so I am not a phone person. That's why I chose to go the Garmin route.
I've looked at the map of my small town and already know the area where they are located. I've been there many times (surprise) and never seen anything out of the ordinary, of course I didn't realize there was anything there to find. So this should be fun. One is basically in the center of town no less. Shocked me to learn that.
So yes! I appreciate all the advice you posted.
Touchstone, I'm meeting with a local geocacher tomorrow at the public library. So that's good advice as well.
I sort of backed into this, it wasn't my plan at all. I do woodwork and made these little boxes that I felt would be good treasure hunt treasures for kids.
I posted on Facebook and was contacted about geocaching. That's where we are at now.
