re: Down da bayou or up da bayou

As someone raised in a city on I-10, I always referred to “down da bayou” as anywhere significantly south of I-10 (not as close as New Iberia, but places like Morgan City, Lockport, Houma, Thibodeaux, Golden Meadow, etc.).

I didn’t know the Piggly Wiggly was the mason dixon line of up/down the bayou.
