Touring the Ozarks

Overheard in Sharps Cutlery Firearms Possibles shop in Norfork, Arkansas, asked by the clerk helping a customer carry four large boxes of ammo out to his truck (maybe 20 pounds each box):

"so are you goin' plinkin' or stockin' up?"

"Stockin' up"

This guy was then seen a mile down the road at a small gas station filling up several large jerry cans with gas. Maybe he knows something we don't...
