Hmmmmm now I have to wonder how cold it will get in the car. I don't know that it would freeze, but am worried of going out there in 2 and a half hours and finding a solid block of Bio Spira........ might go put something over it to insulate it a little.
No, I just went outside though and covered it with a sweater I had in there. Should keep it above freezing long enough, the temperature is right around freezing point. So I think being out of the elements and covered should do the trick for the next 2 hours.
