Paris was crowded along the river, in the touristy zones, but it wasn't crowded at all in the neighborhoods farther from the historic center. It was July, after all, and many Parisians were on vacations out of town. I noticed quite a few businesses that were closed until the end of August, when everybody comes back into the city to start the new work and school year.
