Once again, February is front and center as Museum Month — a time when thousands of family members can enjoy at half price the vast cultural and historical sites in San Diego County. These choice experiences cover everything from ships, space flight, contemporary art, science and even an aquarium. “This is our 22nd year in which we work as corporate partners with Macy’s half-price pass program,” said Theresa Kosen, executive director of the San Diego Museum Council, which numbers 37 museums as its members. “We’re the only city that does something on this grand a scale. And it has increased in popularity.” The month’s activities include such versatile locations as the USS Midway Museum and the New Children’s Museum. It also includes the Museum of Contemporary Art, Birch Aquarium at Scripps Institute of Oceanography in La Jolla and 13 world-class facilities in Balboa Park. Samplings of other museums include “Madame Curie,” the Contemporary Art Museum exhibits of renowned digital-video artist Jennifer Steinkam, with a seven-channel projection inspired by the artist’s recent research into atomic energy, atomic explosions, and the effects of these forces on nature; and the Children’s Museum’s Animal Art displays. The Birch Aquarium will highlight “Seahorses Alive,” featuring more than a dozen threatened species of seahorses and 60 tanks of Pacific fishes and invertebrates from the cold waters of the Pacific Northwest to the tropical waters of Mexico.
