My neice just turned 7 and all she wanted from her Uncle Pagro was a geocahce of her own to be able to check and and see how many people found it. She also has 2 chocolate labs that love to run and play in the nearby dog park. So not being too slow, I put on my thinking cap and set to work.
I got the idea from moparots, who has made some of the greatest hides I have ever seen like Blue Trail in central Florida where I lived until recently. This is a poorly done homage to his skills, but I think I will work on refining the style next time. You are looking for a cleverly hidden locking sandwich container. Difficulty is only bumped up due to the possibility of a lot of barking muggles in the area.
Hopefully this cache will bring the dog lovers and cache finders of this world together and bring a little fun to your day.
