I am starting a new series of events in Savage, MD on September 27 - Going on a Cache Hunt. These events will be set up specifically to guide folks on huts for, primarily, OpenCaching North America and TerraCaching hides. I'm hoping this will be a good way to introduce folks to the alternative caching sites or to help those along who are aware, but haven't quite known how to get started. The initial event will be listed on both OCNA and TC. I'll be hosting a GC meet and greet afterward, which might prove a good opportunity for anyone who attended the first event to talk about their experience.
The first one has been published Going on a Cache Hunt - Sept 2015 - OU0911
The TerraCaching listing is still pending, at this time.
