Rockin' Robin (Code for lock on bird house 729) Traditional Cache

I got this idea from looking around the old garage. I saw that I had some sutable cointainers for geocaching and this one jumped out at me. It has a opening at the top that makes it a perfect cointainer for a geocache and it is the perfect object to make it not noticeable to muggles. 

Green cointainer hanging from tree not many trees in the open so should be easy to spot. Has a Rockin' Robin peeking out the front of the box .  Their is a lock on the side of the box code is 729 when done lock and scramble numbers so muggles cant break in!
