Next was a display describing how and why Philadelphia was chosen as a world heritage city, the first one in the United States. (The second, and only other one, is San Antonio.) Someone else was reading this exhibit and taking pictures as well. That was comforting to both of us.
Finally, off to the side in its own little alcove, I noticed a replica of the Liberty Bell made out of Legos. I thought my boys would enjoy seeing this, and once again I thought it was quite timely, since I've spent more time sorting Legos in the past two weeks than I have in the past two years. I even obeyed the "selfie-spot" sign, so you have proof I was there.
