The city is remarkably clean. The horse drawn carts provide one part of the garbage/recycle system. There are regular trucks that pick up on the major steets. Businesses and residences have certain days and times that they put garbage out on the street and then a truck and runners come by and pick it up. On the interior streets where regular truck traffic is not a good idea, hand drawn carts do the same job. See below.
Street sweepers sweep the dirt and leaves and debry from the street by hand. You can see them working along the sides of the road even in heavy traffic. People acctually wash and polish the stones outside their building. (That's why the floor polisher). On saturday especailly there are all kinds of business cleaning the tile and stone and sidewalk outside of their buildings.
The pictures below were taken on Sunday as we walked to Church. The city shuts down on Sunday. Most roads are closed to all but emergency traffic and major road ways are turned into bicycle ways so people can ride or push strollers or wheel chairs without any traffic. It is called Cyclevia and it occurs every sunday and on holidays. I stopped on the bridge over one of the main autopistas in the city and took several shots so you could see the city scape. (Remember this is our little part ie 2/12's of 1/4 review the last post for reference)
