I was sitting in front of the National Constitution Center and staring at the Independence Hall, thinking about some random stuff. There comes the carriages. For a moment, I felt like being in a scene of the movie “Pride and Prejudice”, when Elizabeth visited Mr. Darcy’s palace with her auntie and uncle. And the next moment, I could almost visualize myself in the 18th century, witnessing the founders of this country gathered at this place, signed the Declaration of Independence, and opened a new era. Hmm, I guess this is probably the magic power of historic sites: you can look back at history as if you were there, witnessing everything.
