Horse and cart.  Early in the mornings you get to see several of this horse and carts especially in the old neighborhoods.  The persons in this carts are known as  fierrero botellero which means man that collects metal and bottles.  Besides metal and bottles they also collect old car batteries, furniture, refrigerators, stoves and anything they think can sell.   You know they are near because you can hear the person on the cart yelling "el fierrero botellero!!" When people want to get rid of old stuff they don't take it to the
dump they keep it till the fierrero botellero comes and picks it up. Before people would ask the fierrero
how much they would give your for something but now I think you are just glad they take it away.
