The Racine class is probably not a geocaching event. Most likely it’s a presentation about geocahing put on by the library (hopefully someone who geocaches!)
I did a presentation at a library about a month ago. It was attended by people wanting to know more about geocaching. Therefore, I didn’t list it as an event (although it would probably have a had a few more people then! 😀 ). It was a very basic presentation with only 6 temporary caches hidden (and pretty easy hides at that), so I could handle it myself.
The Kettle Moraine event is much larger and needs a little extra help. The event listing just helps get the word out and get the needed assistance (thanks to all that are helping!! It’s a really fun time. Wish I could make it this year.)
