I buy my honey from an old man, who parks off of Beach street, off of I-30, most saturdays. He drives a 30 year old van, falling apart, and places his goods on a plywood table.
Most of the honey is in canning jars, with a home printed label. The claim is it is sourced locally, and there are significant variations in color and taste over the year.
Is he scamming me and buying fake honey on Amazon and re-packaging it to look artisinal? Maybe. But I am convinced it is the real deal.

(note my personal belief is that the death penalty is wrong. today, it is legal).
