MR340 Documentary produced by KMBC Channel 9 in Kansas City.
This is one of the best documentaries produced about the Missouri American Water MR340. Led by KMBC producer Matt Evans, this team of six reporters with 8 cameras split into several teams, tracking specific racers and capturing as much of the wide spread of racers as humanly possible.
Here's their home page for the documentary. On this page, the story is split into several chapters. If you scroll to the end, there are several smaller extras, focusing on specific themes and characters.
