Step 6: Final Shots and Placement
Place the log inside, re attach the top of the geocache and find something outside that has a lot of nuts and bolts holding it together (like a water pipe assembly in a park or a metal gate).
Separate the two halves of the geocache and arrange them as if it were actually a bolt penetrating something metal.
Log the coordinates on a geocaching website and watch as the "didn't find it" responses grow and grow.
Behold the EVIL!
