We take for granted many things in America such as the organization of public utilities. In Rio and Buenos Aires things are not always organized. Safety and simplicity are often not the norm. When cable TV came to these cities, wires were strung everywhere. Check out some of this mess.
Need a cable connection? Just shoot a wire from building top to building top.
It’s a spider web up there.
Install a metal sign attached to a metal awning inches from the electric wires – no problem.
So much for one wire for the entire block.
