Visited LACMA a couple weekends ago and thoroughly enjoyed exploring just one of the many buildings. The only other time I had been there, Molly and I saw the Vanity Fair exhibit. Here are some photos my most recent trip...just a couple of favorites. Learn more about LACMA here.
And a web site to help you organize your summer museum visits...search by state, category, etc.
