San Francisco 2011

As a retired biology teacher, but still active with the New York Science teachers, I attended the National Science Teachers Association (NSTA) conference in San Francisco last week.  The site was excellent with the hills, cable cars, Golden Gate Bridge, the diversity of people, excellent food, and of course the conference.  I took over 300 images and am now trying to decide how to use them in montages.  Here is one idea using several layers of extracted buildings.
