The physical location of the puzzle box is just inside the fence of private property. The property owner knows the cache is hidden there, and the person who looks after the property (me) also knows it's there. You shouldn't have to go through the gate to retrieve the puzzle box, but if you do use the small gate and please remember to close it - thanks.
The cache container is a puzzle box I have built. It has a locked lid and a locked drawer. The lid is locked with a padlock and it is not apart of the puzzle (I use it to access and reset the puzzle). To log this cache you will need to figure out how to open the drawer to sign the logbook inside. (you will need to take the cache with you to do this). To solve the puzzle you may also need the use of a computer and it may take 1 or more trips by car in the Lac Le Jeune area.
Once you solve the puzzle and sign the log book you will need to return the cache container to where you got it from and then place the TB "BugDuino II" in an LLJ cache or you may hand the cache and TB "BugDuino II" off to another cacher. Please keep the TB with you while you have the cache and release it after you replace the cache.
Note: to get hold of the physical cache container you need to first find "BUGduino II".
But you do not need BugDuino to solve the puzzle.
If CacheDuino II breaks or doesn't work as you expect it too, please contact me so I can fix any issues.
