The Eiffel Tower popped up again over by the Arc de Triomphe. A good subway line is something that I miss living in Portland. They can be so incredibly convenient - not that I used the Metro in Paris too often as walking was such an exciting adventure. But still, there were times it came in pretty handy. And maybe this is a misperception on my part, but the Metro in Paris seemed much more affordable than say the tube in London, which surprised me by how expensive it could be. To further compare the two cities, the Metro in Paris could also be quite an adventure. It was not uncommon to see street performers jump onto the Metro and put on impromptu performances, so most rides were accompanied by music. In London everybody got real quiet on the Tube, burying their faces in newspapers and magazines. No music. Barely much talking even. At least that was my experience. It was an interesting comparison.
