 Those with a perfect record of attendance have their name inscribed onto a Plaque in Smokey Joes Bar.Taking advantage of Penn's location in the city of Philadelphia, members of the senior class don Walnut Walk themed shirts and embark on a day-long, citywide pub crawl, starting at 2nd Street near the waterfront and moving westward along Walnut Street until participants arrive at Smokey Joe's on 40th Street, just south of Walnut.The event is one of the highlights of "Senior Week," in which seniors celebrate the end of their time at Penn.
