Despite the lack of cold weather, Lake Accotink Park stayed open late last weekend, giving visitors a chance to look at the park under the night sky as they searched for owls and other nocturnal creatures. After walking through the park, guests were treated to hot cocoa. The park is offering another night hike Friday and Saturday, Feb. 16 and 17 from 7:30 - 9 p.m. For more, call 703-569-0285.
