My boys would love to watch what's going on at the construction site today. A new wing is being built here. On the other side of the site is a crane. From that side of the building the crane operator will pick up a large box (bigger than your car) and blindly bring it around beween the two buildings and down to the 5th or 6th floor. Okay so there is a guy with a walkie talkie telling him what to do, but the crane operator can't see this side of the buildings. The workers who are attached to the building by harnesses lean way out and grab the large box and pull it into the building. Then it happens all over again.
