Riverside Art Museum
Located in Riverside California, the Riverside Art Museum hosts all the usual suspects... and the website does likewise. A simple layout with main navigation across the top, the CSS is as basic as it gets. Subtle sub-nav, lots of pictures, and just enough text surrounded by lots of whitespace.
The only thing I don't like about this site is that the Blog page takes us out of the normal flow of things.
If only my K9 site could be this nice....
