Although the information that was shared in the panel of historians and architectures was repetitive information that we had already learned in class, it was interesting to see  how in depth one can go when discussing grand central.  One interesting idea  that they brought up was the comparison between Penn Station and GST.  They argued that Penn station was a standalone building as appose to GST which contained shops or as they stated a choreography of connection.  They also debated on how Penn station was a necessary evil  for the preservation movement to rise; thus  thanks to Penn station we now have GST and other landmarks.
