Hi! Welcome to OCDO. I live just south of Sanford, both my wife, and I OC. NO problems at all, not unusual to have people thank us. We shop in Walmart, Food Lion, and many other businesses in Sanford, very few are posted. We have never been asked to leave because we were armed in Sanford. You may see us, just look for the armed Santa Claus.
NOW Fayetteville there are people who OC, and I OC, but you sometimes will get the stink eye. There are a lot of Yankees that are in Fayettenam. The Mall is now posted, after a incident with a Soldier lawfully carrying a rifle was arrested for GATTTOP. Assuming the posting was because the arrest went no where. We only go to Fayetteville when we have to, but we have had no problem with Restaurants there.
Anymore you can find almost anything you want in Sanford that you can in Fayetteville.
