Just like the title says, choose any where (or wheres) that you would love to see a tag placed, or discuss the locations other people have placed.
I already know we'll get the "My doorstep", "In my mailbox", "My house", etc. comments, but please try to refrain from them and come up with somewhere interesting, related to the game, or completely unrelated.
Feel free to post a picture of the place, or even why you chose that place (Ex: For the Moon, does the Gears Universe have no Moon? If it doesn't, now it does.)
If I could choose the place a Cog tag, I would choose to place the Cog Tag on the Moon. (Making the picture at the moment in Photoshop).
