You are looking for a large, metal ammo can. A special tool (for climbing) will be helpful. At least bring a tall friend. To take credit for this find, you have to sign the log. Guessing where it is, or seeing it from a distance, will not count as a find. If your team name is not on the log, the log will be deleted.
Congratulations to Team Spank8401 for a well earned FTF!
