Leaning against a scrub pine as preschoolers scurry about at his feet, Shane Gazda, father of 3-year-old twins, recalls a conundrum he faced earlier that morning: whether to take his Smith & Wesson .40 caliber handgun to a Groundhog Day celebration in this town’s White Deer Park.

After all, what was once against the law in North Carolina – carrying a concealed gun in a town park, square, or greenway – is now, as of Dec. 1, 2011, very much allowed. To Mr. Gazda, who likes to shoot targets in his backyard, an event as innocent as paying homage to a rodent could turn dangerous if the wrong person shows up.
