A local Geocash enthusiast, that I met a while back while promoting disc golf, has asked me to pass along information about an upcoming event. It is called "The KC Disc Golf And Geocaching Mashup".
It is set to take place at "Lake Olathe from 8AM to 5PM on the 22nd of June". From the sounds of things it combines Disc Golf with Geochashing. It sounds like it could be pretty interesting, however I will not be able to attend.
