Right, but now that you've said "black market," I'm curious about how you're using the term and how your former employer (who I assume was the government) used the term. To me, a black market is just nature healing. But when most people say it, their butts pucker and their eyes go round.
Maybe the place with the expensive sandwiches was richer than the other place.
Or maybe that town had a meat packing plant and the other didn't. Futures should've smoothed that out, but idk, maybe. Utah is closer to the Mississippi basin than Oregon, which is where we grow most stuff.
