2008's field of almost 100 Iditarod mushers set a record. It also made 2009's field of 67 seem unusually slim. Some have speculated that the slim pickings are due to the current economic downturn. If that's the case, I'd like to credit that same economic downturn with the fact that, at the time of this writing, not a single musher had scratched (dropped out of the race).
In a race where competitors occasionally drop out before the official restart, that's a surprise. I wonder how long they can keep it up?
