This is a small size ammo can that contains books. All the books are in gallon size storage bags to further protect them from the elements. If you bring books to trade I'd recommend paper backs since the cache isn't that big. I am hoping to get a bigger cache container and I'll try and keep it stocked with books.
I am not sure how accurate my GPS was among the trees but the spot struck me as the most obvious place for an ammo can and I am hoping others will zero in on it as well.
