Apologies for posting such a non-Switzerland related question on here, but I thought there might be some folks here who have been to Philly and could advise me.. I'm off to philadelpha for work and added 3 days of holidays. What are the best things to do there? I'm not all too interested in American history, I'm afraid.. Thus, (apologies to the Americans on here) I'm not keen on seeing the liberty bell, the Franklin museum or the State Penitentiary..So far, I want to do the Mural walk and visit the art museum (including running up the steps..

)
Any tips welcome...
