To claim a find on a cache you must find it and get your name on the log. Many caches do not include a pen or pencil so when geocaching you should always have at least a pen. An extraction tool would be another good TOTT to bring with you, but this cache is about signing the log. If you do not get your name on the log with a pen, pencil, marker, stamp or otherwise then do not claim it as a find.
To earn your smiley on this cache find it and sign it with your own writing implement. To find the cache look low in the tree. Stealth will be needed with the number of people that visit the park and the wild animals with bushy tails that live there that will be looking for a free hand out.
