Perhaps D.C. Mayor Anthony A. Williams had good reason to stick by embattled Department of Parks and Recreation Director Robert Newman until his resignation last week: According to the city’s official Web site, www.washingtondc.gov, as of Monday, each of the 77 D.C. recreation centers featured state-of-the-art facilities. “Our Water Aerobics and Deep Water Exercise classes can provide a high intensity, low impact, full body workout,” the Web site said about Kennedy Recreation Center, at 7th and P Streets NW. “Isn’t it time you take the plunge?” If you did, you’d suffer injury: Kennedy lacks a swimming pool. So do many of the city’s other rec centers, all of which had identical write-ups. Local swimmers might be better off at Fairfax County’s George Washington Recreation Center, which has a verbatim description of Kennedy’s amenities on its Web site—but this time they’re for real. Fairfax’s Web site was being used as a prototype for D.C.’s, and material from it was mistakenly published, explains Linda Argo of the Office of the Chief Technology Officer. By Tuesday, the phantom pools had disappeared. —Elissa Silverman
