Logan's burial might be considered a turning point in the novel because it is the point at which the democratic process and reasoning are completely abandoned for the attitude that force matters more than good intentions do.
Porky's burial is the first time that Randy actually has to force people to do the right thing. Porky's body is a menace.... it could cause an epidemic that could affect everyone, and no one wanted to be a part of it.... but Randy got it done, and he had to pull his pistol to do it.
The last sentence is significant in illustrating the road ahead: "The engine started and Randy turned away to face the thousand-year night"
