I do all the grocery shopping as my wife hates it, and well, I like to eat. OC when weather is nice, nobody notices, all busy with their list, phone, kids, whatnot. Kind of funny how you can walk two feet past someone and they have no idea there is a firearm. Part of it is how close quarters are, easier to see from a ways off. Kids and sitting people notice first. I bet I'm in WM for an hour and maybe 5 people notice. Maybe some I don't notice, but lots that don't have a clue.
OC is pretty rare around here, or maybe I'm not noticing either.....unusual but nobody gets excited pretty much covers it here.
