It's not about color, it's about cajun. I asked for directions there once. After the guy was through explaining the way to go, my wife asked me "Did you understand that?" and i started laughing..."not a word!"
LOL!
One of the pleasurable perversities of the hillbilly mind is giving "interesting directions" to tourists.
"Well, first you go 'bout a quarter mile past the old oak tree that burned up from lightning strike last fall and make a right at the stone fence that a farmer hauled away to build a barn and then make a left when you see that big Angus bull that won 1st prize at the county fair. If you see a Hereford bull or a henhouse, you've gone too far and you gotta turn around."
Unless you've been here your whole life and know the area's history, none of it ever makes any sense.
