Hard to believe that Sesame Street, the block where Generation X’ers learned their ABC’s and 123’s, is celebrating its 25th birthday. Though the years have been kind (virtually all the original cast remains), this season things are a little different in the old neighborhood. Just around the corner from all the regular haunts-the Sesame Street stoop, Hooper’s store, etc.-there are new buildings to visit and new places to play. Above, Kids Extra takes a special tour of the set to check out the additions.
