As our bus of the “Bigbus Tour” entered the center of the city, it was really so awesome to  travel in the midst of these modern and incredibly beautiful Skyscrapers of Philadelphia. Wow! in certain angles they seem like mirrors  reflecting the sky, another building and the light that changes at different moments of the day seemed to give a new color to them. Skyscrapers like these can also be as interesting as some some historical buildings in Europe.
