Ray's got most of the story right - and the rest of you are closing in on the true scoop, too. About the only thing worth clarifying is that sunrise (per se) is about 7.15AM MDT, and we can guess that it'll be light enough to race sometime about 7.30 or 7.45. Or so. When Mike Cook was going through the meeting he asked if there were any particular requests -- like "who wants to run first?". Well, what he really said was "Who wants to run first, RON?!" as he looked at Ron Main. Main is well-known for wanting to get racing as soon as the track is open.
By the way, the bike racers from down under are Kim Krebs (forgive me if I've got her name misspelled) and Greg Watters. They were here at WoS and stayed over for this event. Rocky Robinson has just posted a long note on his Facebook page telling why he's not going to run this year. Get over there (assuming you can - I use Nancy's FB page to get into that stuff) and see what he's got to say. I'll ask him to copy his post to here. He talks about Sam Wheeler and Gabriel Uttley - and gives some interesting background.
So - look for the Poteet and Main team to be on the salt at o'dark o'clock, prepping the car for a run. The car is absolutely ready right now -- just needs the ice added and so on. I figure they'll head towards the Floating Island end of the track by 7 or so - and then, once they're at that location - wait for the sun to lighten the track enough to race and maybe the wind, if there is any, to be proper for racing.
But - but - but --- FIM Charlie, a/k/a Charles Hennekam, was introduced as the guy that'll be on site to not only officiate for the bikes - but also the cars. I'm not sure about that being correct -- I thought Dave Petrali, of USAC, was the FIA representative on site, but that's not the way Mike Cook explained it. And Charlie isn't expected to be on the salt 'til morning, and - if he is the FIA rep - then no cars can run until he's there. And I don't have any clues as to when he's going to arrive.
So therefore I say unto you -- we don't know when things will start happening, either. All I can do is tell you to plan on being near your computer by 7.30 or so MDT and start clicking the refresh button. Nancy and I will be taking notes and making posts. 'Til tomorrow, then, hokey-dokey?
