IN FAMOUS, picturesque Bucks County a new Levittown is rising. All the resources, all the experience, all the talent of the world's greatest community builders—Levitt and Sons, Inc.—have been marshaled to make it the finest town in the United States!
   Everything that made Levittown, Long Island, internationally famous will be here but much better. Swimming pools, athletic fields, baseball diamonds (for the Big Boys and the Little Leaguers), playgrounds, the town community hall have all been carefully and conveniently located.
   Road layouts have been planned so that no child crosses a main road to reach school. Wide, parked boulevards crisscross the town to make every house easy to reach. Even street names have been keyed to make sense. For instance, Sweetbriar Lane (and any road beginning with "S") is in the Stony brook section.
