The "race to the finish" usually starts around page 200ish. It's usually a blitz - people posting random funny pictures, vacation pictures, odd bits of nonsense. Don tries to start the new thread during that time. The moderators will shut the thread down somewhere around 250 pages. Sometimes later, depending on how fast we're moving and if they're paying a lot of attention at that time. It's not uncommon to blow through 50 or more pages in just a few hours.
