One case of Kentucky Delux.
Cheap whiskey will bring top dollar in barter.
Bartering with people means you have a conversation with them, a sort of respectful distance.
How do you barter with someone who just smashed your bedroom window in the middle of the night? Or tossed a firebomb at your house?
Whiskey will be valuable. But the most valuable things will be common sense, reason, planning and hope.
