This trip has been wonderful. That said, there's a lot to say for staying home, especially these days. To give examples, in the following posts, I will tend to display not only my own pictures, but other's pictures as well, especially displays in museums. Honestly, as great as seeing the real things are, I often prefer to study great paintings on the internet. Google Art Project (just as one example) displays ultra-high resolution famous paintings. http://www.googleartproject.com/ and with these, there's no standing in line, there's no paying to get into the museum, and best of all, you can have a sandwich while you study. They won't let you carry a sledgehammer into the Louvre these days, much less a sandwich.
So, travel, through the internet. No language learning or missed trains required.
