You're looking for a container, (approximately a gallon) wrapped
in cammo tape, containing a log book, random Travel Bugs, Coins and
small items for trade.
It would be ideal to leave a TB/Coin when taking a TB/Coin so
there is always at least 1 or 2 goodies for the next cacher, but of
course it's not mandatory.
This cache will eventually appear on my Mad Cacher
GeoCaching Blog at
