This is a fun puzzle that can be solved on the spot. No special skills are needed.
The container for this cache is placed on the utility pole in the alley behind my house. You must look at the tree in the yard (there is only one tree) and count how many cats are in the tree. They are all together and can be seen easily from the alley. Using this piece of information, you must determine the 3 - digit combination to the lock on the container.
For the FTF there is a cat magnet.
