Usually there are a bunch of caches published by people specifically for the event. They are published on the Wednesday or Thursday night, to give people time to solve any new puzzles. On Friday, at 6PM, you head out and search for these newly published caches (but not before or you risk being called a hoser). You will more than likely run into many other cachers out seeking these until the wee hours of the night. When all the caching fun is done, we call meet on Saturday at 6PM, and the posted coordinates of the event (which is not published yet, but it will be the same place as previous years, the coordinates on the beer case above). We eat, chat and award a few doors prizes, and you get to log the event as a find. That's it. Easy peasy.
