Right now you're probably asking yourself: "How could there possibily be any good news?" The good news is that it is only a D2. With all of the above, you're probably asking yourself, how could it be a D2. Here are my reasons: it "is not in a tree"; GZ is not cluttered with potential hiding places; your geosense, or at least your common sense, will limit the possible hiding places very quickly; it is winter friendly; and, it "is not in a tree".
Some cachers don't like nanos or micros in trees. I'm not a great fan either; however, I must admit that when you do find it there is a great sense of satisfaction with the find. This is not a nano "in a tree" so no whining about that aspect. It is a nano so you have the choice of not looking for it ... but what fun would that be.
You might need TOTT but definitely a writing implement.
