Hasn't changed in all these years I see. As I recall that street was full of galeries of good images of the west and wildlife. Have to return someday... soon.
it was an inspiration to see for sure, 3 floors of great pictures, on the bottom floor they had massive prints and Mike coined the term "Print it big and charge alot ! " we were joking about that the rest of the trip
If you are traveling through the airport in Denver, there is a Mangelson Gallery in the main terminal. It is interesting to see what he sells. Some images really break the rules and would probably be pretty heavily criticized on BPN.
