I remember considering this ages ago because I like walking anyway. How did you get started? Thanks for reminding me about this. I'm going to look into it now.

My nephew used to do this in the early 2000's. I don't think he does it any more as he's always flitting from one hobby to the next. It does look interesting though.

I have an online friend who loves to do Geocaching! I tried once to find something that was in my local county park, but I couldn't get a good cell phone signal to get the right coordinates. So I never found it and I heard later on that it got flooded out.

No, I don't use it. The last time I tried making use of it years ago, it wasn't that interesting to me and it's why I have never bothered about it ever since. 

Some years ago, it was something that mattered much to me because I used to get into Geo-Caching very often. But after some years, I have given it up as I completely lost interest in doing it.
