I was the second pair out at 8:20 AM. My whole roof was solid white with ice, all sides and rear windows had ice, couldn't put a dial on the car as it just turned into a blob of white. Dial only on windshield. Following are the numbers I got from my sling psychrometer about 5 minutes before launch.

Wet temp 37 degrees Dry temp 39 degrees Dew Point 34 Humidity 83%
Wind none barometer 30.20 Density Altitude -1374 ft. Relative Horse Power 106.9%
Air density .0796 Absolute Air Pressure 30.02 Vapor Pressure .1955

At about the 1,000 ft mark people saw a large flame come from out the back of the car. Turned out to be the ice from the roof had blown off and reflected off of the sun light looking straight at you going down the track. Casey Miles was the next pair out and said he was spinning at the 1,000 ft mark, think he was fibbing though.

Two years in a row with ice on the car for the first round, just doesn't get much better than that if you like cold weather. Maybe someone out there will take pity on me and get me an enclosed trailer, but then I do like open trailers.
