How would you explain ‘bicycle cart’ in the context? The Zócalo is a huge square with palm trees like parasols. Facing one side is the long Palacio Nacional of pink stone, with small windows all the way down it like holes in a flute. The brick streets leading into the Zócalo are narrow as animal burrows in tall grass, the buildings close on both sides, as far as you can see. Downstairs are shops and people live above, you can see the women leaning on their elbows on the iron balconies watching everything below. Bicycle carts, horses, and automobiles, lines of them, sometimes going both ways in the same street. How would you explain ‘bicycle cart’ in the last sentence? Thanks!
