Welcome to the Trophy Challenge series of Challenges...
This series is based on variety being the spice of life!
To claim this cache you need to have found 15 caches on their Birthdays (date placed) from 1 to 15.
This is a gadget cache, so make sure you come prepared... 9v battery (the rectangle one) and a piece of wire or 2. Read the hint also...
The bird box conatins the key for the container which holds the log, both containers are up different trees, so you will be up, down, up, down, up and down.
Do NOT try to force anything, just a small pull is required, once you figure out the combination of course.
You will notice a small 35mm film pot attached to the top of the bird box, this contains a piece of wet & dry sand paper, if you decide to use this, please return it to its little container for future use.
Here is a challenge checker to see if you qualify...
