The National Gallery of Art (NGA) is one of the best museums in the world. It is probably my place to visit in Washington, D.C. Incredible art everywhere - wow - what a great collection of masterpieces in a lovely setting.
I visited the NGA at the conclusion of my obligatory annual family visit to western PA in October 2011. What amazes me is that for the first half of my life I knew absolutely nothing about art (except for my velvet paining of the dogs playing poker!) and now I appreciate it so much.
This is definitely a must see destination in D.C. - please check it out and support the arts!
