Has anyone ever organized a Geocache event for a school? We are thinking of doing a scavenger hunt and I thought geocache might be the way to go. My family loves to Geocache but I have never hid one myself or organized an event. I suspect we would have between 150-200 kids and adults at the event. How would I best organize the event so it is easy for a kindergartner and still fun for a 5th grader??
