Education was the key concern among Ward 3 residents who attended last night's Neighborhood Citizen's Summit at the Metropolitan Memorial United Methodist Church, where D.C. Mayor Anthony Williams spoke about the challenges and solutions that face the District. Among other concerns was an Upper Wisconsin Avenue development, the support for Advisory Neighborhood Commissions and the displacement of lower-income families from the D.C. area. However, the mayor also extended his vision of a changed and connected D.C. with better overall standards of living going into this century. This includes the addition of 100,000 residents, which some questioned because the increase will add to the already existing problems if they are not fixed.
