If you have ever wondered where all the geocaches are in Wisconsin, take a look at this. 
I posted a similar map about five years ago, but I decided to see what has changed since then. Overall, the hot spots have grown in size, but the general look is pretty much the same. The geocaches are where the people are.
That is really cool. I’d like to see the side by side comparison. I like to think I make the south central state-line a little bit more of a “hotspot”. Haha
