Paris Streets Can be Hard

Boulevard vistas and uniform facades, above, were created by Baron Hausmann in the 19th Century. Washington DC was modeled on Hausmann's Paris. Today Paris (and DC) have car traffic that has to negotiate the diagonal boulevards.
Paris, below, has a weekly roller blade event that closes streets as the thousands of participants roll past.

There are quite a number of homeless people evident on Paris streets, despite generous social services. The two ladies below are doing their wash in water running in the street gutter.

The wide boulevards are also inviting for walkers with their dogs.
