Events encompass the social aspect of geocaching. Geocachers get together to trade travel bugs and exchange tall tales. Experienced geocachers pass on their pearls of wisdom to newbies and everyone compares GPS units. Every level of geocacher is welcome; food is often involved.
Once an event reaches critical mass (500 geocachers), it becomes a mega event. Once an annual event reaches mega event status, it will always be rated as a mega event.
Both events and mega events are posted on Geocaching.com. To find them, look on your profile page and look at the column on the left. Under “Search Options”, select “List Newest in — ” (in my case, Texas). The events icon looks like a speech bubble. Check the distance from you before signing up for an event; I get events from over 200 miles away because they’re all in Texas. The events are listed according to date; events occurring “later” will be at the top of the list.
The Texas Annual Challenge reached mega status in January. Despite the dreary weather, over 800 geocachers attended the event at Lake Ray Roberts State Park.
