I work for a living, but in the off times I still play with this technology, so I have a Premium Geocaching subscription. This allows me to query their data in circular buffers and return a GPX file. After about 27 of these queries, I was confident that I had all of the cache locations I wanted. Running a few geoprocessing functions, I dropped any duplicates and union-ed these points to county polygons to get the number within each county. This data are reflected in the Classified inset map. What am I talking about? Geocaching of course. If you're reading this tech blog there's a pretty good chance you already know what geocaching is...
