I am traveling to Italy this spring and i would love some advice about what to know and expect. Anything about culture, etiquette, good resources for history, and what artists' works are prevalent so I can read up on them before I go. Please don't just google and paste a website link, I can do that. I am looking for books, videos, or really good websites you personally recommend. Thanks in advance for helping me not be an ugly American tourist! =]
