I am sure people have noticed the great reflections you get from the Gene Leahy Mall,

You should check out the reflections provided by the new UPC. It's a very reflective building. You can really capture FNC and the US Federal building quite well on the west side.
"The right to have access to every building in the city by private motorcar in an age when everyone possesses such a vehicle is actually the right to destroy the city."
