Philadelphia: the most important city for the USA

I went to Philadelphia in July with my family and I loved it from the first day i was there. I was really emotioned when i put my feet where Abrahm Lincoln and J. F. Kennedy announced the rights for black people in front of the Independence Hall, in which was signed the Declaration of Indipendence. The history of Philly is really important for me, not only for American people. Watching the bell that announced the liberty from the Great Britain was intresting. But the most important thing was that museums in Philly are free, and this is wonderful for turists! I hope to have convinced you to go and visit Philadelphia!
