Here's one for other geocachers books. It's a roach geocaching container. Place this little container in a depression in the ground and all you will see is the roach.
The cache itself is a waterproof tapered pop top container glued with all weather adhesive to an approximately 1 1/2 inch x 3/4 inch cockroach geocaching container. You’ll also receive a log to slip right in your container with plenty of spaces for geocachers to sign.
