I had an idea to build an underground box of some kind...if anyone seen lovely bones...kinda like what the old guy lures the little girl into and coating it in some kind of protective waterproof casing. This does involve a shovel and digging but it would just be for the hiding place. You would not require a shovel to dig it up because I was thinking, put a door or something of that sort to get into the geocache so it is easily accessible. Kind of like a cellar I guess. I'm not sure if this would go against the rules or not so if someone could help me out that would be great.
