Question: How does one know what sweaty Sasquatch anus tastes like?

Water can be locally sourced, and if the beer is left in a stream long enough, it'll be cold enough to be drinkable.

We used to use one of those food sealer things to make "booze bags." Those, and some good powder drink crystals and a water filtration system, made suitable refreshment after a day of hiking to a remote spot to camp.

These days I stick to car camping - well, actually, I stick to the back balcony and a nice cigar. :-)
