(Read about Parts 1 and 2 of our trip.)
I was blown away by the Smith College Museum of Art. We could have easily spent two hours on just the top two floors of this museum alone.
They have a tremendous collection of 19th-century French paintings (including Monet, Seurat, Renoir, Gauguin, Cézanne) and some excellent American art as well.
All in all, this museum offered much more than I was expecting to find on the campus of a small western Massachusetts liberal arts college.
If you go, make sure you use the bathrooms in the basement. They alone are worth the (very modest) price of admission.
