Market Street was all swiveling hips and snapping fingers last night during a rockin', rollin' block party.
The four-block jam was the highlight of Day 7 of the Welcome America! celebration, an 11-day orgy of parties and special events to commemorate the opening of the Pennsylvania Convention Center and the Fourth of July.
It was curb-to-curb people as thousands turned out for the festivities along Market Street, between 9th and 13th streets.
Jugglers and an Uncle Sam on stilts moved through the crowds. At a booth, children got free facepainting, while clowns gave out fanciful balloon sculptures.
