Once, on a five nighter into the backcountry of Yosemite, we met a friend who had come in from a different direction. While sitting around a fire that night he produced a fifth of Jack Daniels, IN THE FACTORY GLASS BOTTLE. Kind of amazed me that it was still in one piece. Then we became concerned about the weight he was packing, so, even though Jack is not my first choice in toddy making, we helped him lighten his load a few ounces. It did go down nice, although I would really recommend a non-breakable container...
