Probably the most important piece of equipment for Geocaching is a PEN. Its quite possible to find a cache without GPS, but you can't sign the logsheet without a pen to prove you've found it, SO TAKE A PEN
This cache may or may not include a pen, and if it does, it may not work, SO TAKE A PEN, no excuses. Anyone claiming a find who doesn't sign the logsheet, or post a picture of the logsheet will find their log magically deleted....
