Piggly Wiggly is headquartered in Keene, N.H. In NH, if you are a resident, you don't need a permt for ANY sort of carry--CC or OC. They have some of the best carry laws in the nation up there, and actually believe in the Constitution and liberty.
You might contact Corporate, and see if this is coming from the top or is a local or regional thing. I'd find it hard to believe that it's coming from Corporate, since NH is one fo the last bastions of Constitution-believing Liberty-minded people in the Republic...
If this is coming from Corporate, I think we need to contact the "Ridley Report" folks up in NH. The would be all over this, and I'm sure they would quickly stage some sort of action to bring Piggly Wiggly's action into the public eye.
Big companies usually sneak this sort of thing in, and hope people will just "go along". Since people tend to not want to draw attention to themselves in our current dumbed-down, passive, sheeple-trained society, anti-gun "sneak attacks" like this usually are successful unless we mobilize QUICKLY, with large numbers, and MAKE IT PUBLIC.
The recent Starbucks situation was a great example of this. The Bradys were trying to sneak a ban in on us, but the OC and CC community mobilized quickly and put the anti-liberty Bradys in their place...
