You are looking for a camo gallon plastic jar. Plenty of room for swag and TB's and geocoins.
There may be muggles about so use stealth if you have to.
Even though I included a pencil, it's also a good idea to bring your own writing utensil just in case.
Congratulations to wis backpacker for the FTF
Winter friendly rating: Can be done if the snow is not too deep. May need snowshoes in deeper snow.
