Same as how you will have to work to find a real starfish around here you will also have to work to find this hand carved starfish stamp. It won't be too hard though. Just start off at the posted coords and follow the pictures until you finally locate the cache. Please don't take the stamp or inkpad as those are need in there for this to be a letterbox.
...oh and we realized we should have added a book instead of a log sheet when we got there, We will change it next time we are there.
Hope you had a good time!
