Events are a great way to put faces to names you see on cache logs and get to know one another. The first thing you'll need to do is "Log Your Visit" and choose "Will Attend" so that the host(s) will know how many folks plan on coming. Once you've attended the event, signed the on-site logbook and are ready to 'claim the find' online, just choose the "Attended" log, write something up and that's it!
The event will have a log book for you to sign, friends to chat with, TBs, coins and path tags to trade/ discover; and caching stories to tell.
If you've never attended an event, please consider this one, we are particularly newbie friendly and love to see new faces!
