Given the name of the road to this area, I knew the cache couldn't be anything less.
This road doesn't lead to much of anything except an empty cul-de-sac.
The container is of course, an ammo box, albeit a plastic one from a local brick and mortar store. But it should hold up well to the elements.
There is a ready-made preformed bottle for the FTF. It may need a little bit of camo before placing it, if preferred.
Please be sure to re-hide Cache so that it cannot be seen.
