The old and destroyed school bus from "The PTA Disbands" is at the school playground.
Beyond the lift bridge, the "636" area begins, full of mansions like Burns's, Mayor Quimby's and Kent Brockman's. This is where the Stonecutters building is too and the hidden tunnel is next to it. It connects with the power plant.
In Homer's workstation at the power plant, a lever has a block hanging from it.
The run-down area has no sidewalks, open sewers, small roads, destroyed houses and shacks (like Nelson's, Moe's, Cletus' and the trailer park).
In the Bonestorm Storm mission, the man driving the van is Jasper Beardly.
