you know, change is hard. I am an archaeologist by profession and is always hard to see something old get replaced by something new. What was there before tells us so much about our past.
I remember when I was in Egypt in Alexandria and was watching a construction crew building an apartment complex. They were digging out the foundation and had found a 3rd Ptolemaic temple. I don't even think they waited a week before they had filled it all in with cement so they could finish out the apartment complex. Progress.
