Just off the phone with Max Faasen at the track, he said the track is dry and the grounds look real good.
The forcast has not changed, mid to upper 40s is completely workable guys. I have miles of laps and tons of video to convince you.
I do have a tip for you to keep your hands and fingers warm. Wearing rubber mechanic/surgical gloves under your driving gloves will keep the cold air from freezing your fingers! You can do serious damage if you are not careful. Harbor Freight has these gloves, I use the black HD model.
I’ll be back again this evening with a final look.
