Sinatra tells the urban planner she wants a city to house 25,000 people. The urban planner replies that she would need space for a town like Toledo, Ohio. Actually, as of the 2020 census, Toledo had a population of over 270,000...but that is not a mistake. She asks what it would take to sustain a city of 25,000 people and he says an area the size of Toledo. Not just the 25,000 people, but for the farmland and the infrastructure and the power supply required to self-sustain 25,000 people.
As Collins and Sinatra drive towards the mountain, they pass a fleet of parked heavy construction vehicles. All the excavators on the right side of the convoy have their booms hanging in the air instead of having been lowered to the ground.
