I guess the best coctail I've ever had in the Bwca has got to a Dry Ice Martini.
It used to be I would eat poorly when in country. But as ideas progressed we figured out how to eat WELL. Dry ice is definately extra weight I don't mind having to carry. Nothing like being able to eat ribeye for supper 4 days in. One small cube or some shavings in a nalgene bottle with some stoli and a little vermouth, well shaken in a coffee cup is all it takes. ;)
