I was at a cache today and picked up at TB with the goal of visiting all 50 states. This particular TB has been in Maine for a while. Should I simply drop it off at the next cache or a newer cache in the hope that it may move out of state or is it permissible to go to a cache like the BIA TB Hotel where it tends to have a lot more action (and in particular out of state action) and drop it in . . . conversely if you drop one in, can you pick another up? If the answer to this is in the affirmative I would assume that you would simply not log this as a find, but only as a posted note.
