Caption with photo in print edition: Kathy Switky of Menlo Park sent us this photo of a sign on the Menlo-Atherton High School campus that reads: "Visitor's must register in office." She posted the picture in the Almanac's online Photo Gallery with this message: "Apparently the English teachers at MA have given up correcting apostrophe abuse." This sign went up in 2009 when the Performing Arts Center opened, she said. "I can't believe it's still there. I have been tempted many times to go over there with an appropriately-colored Sharpie, but was afraid I'd be cited for vandalism on school property." The Almanac attempted to get a comment from the school without success. But it is summer, after all.
