The note is located under the elevated highway east of Quincy Quarries, next to the skeleton of Charles Dieter Jr. (the author) along with the Neponset cabin key. The skeleton is located under the section where the broken section bends downward, near the yellow bulldozer on the truck and trailers loaded with stone blocks.

Rot in hell, you bastards. And you can join them, Carol.
