Trent at 2015 Ceremonial Start above.
The ceremonial start for 2016 is being video-streamed live. I thought it might be open and available but it looks like you have to be an Iditarod Insider to watch. First musher went out at noon MT. Trent with Bib #58 will go out sometime about 2 MT. Sign up for Insider status on the Iditarod website (iditarod.com) if interested (you get the race GPS tracker and lots of interviews and footage).
