When you’re an “Action News” reporter like guest critic Lauren Wilson, you know there’s real danger of bringing the bad news home with you. Wilson unwinds at picturesque Battery Park on the Delaware River in New Castle, where a playground, a small sandy beach, picnic areas and a paved trail make for fun and relaxation. “It’s a great, quiet place to sit and clear your head,” she says. “You can walk off your stress on a scenic path by the water.” There are even weekly open-air concerts in summer.
