Welcome to the Little Big Econ State Forest!
This is a letterbox hybrid. A stamp is in the ammo can and is not to be removed.
Are you familiar with Nightmare Alice? She is a character in the Lil’ Abner cartoon. Like the Alice created by C. S. Lewis, who had issues with rabbit holes, Nightmare Alice was oft beset by potions. Being a witch, Nightmare Alice’s potions were typically geared toward ensnaring the affections of either Lil’ Abner, or Dr Babaloo, as well as other evil deeds. You can read the rest of her story, and how she became transformed into the large alligator who lives nearby, at the posted coordinates.
You seek an ammo can, at the posted coordinates. When you get to the posted coordinates, find a comfy spot, as you might be there, for a bit. Inside the ammo can, you will find a bit of a cantankerous puzzle, you will need to resolve, in order to locate the final, a second ammo can. Please restore the puzzle to the condition you found it in, so others can share the adventure. Your best bet for traveling to the two stages, are by kayak, though, technically, you could hike there, if you don't mind getting your feet damp, during the rainy season.
