Tomorrow it is supposed to continue to drop to -15, and I don't plan to go out unless my power goes out.

Is it a good idea to start my car from time to time and run it for 10 minutes? I want it to start Tuesday, assuming my office is open, and want my car to start. The high Tuesday will still be sub-zero.

I hope there are no power problems, I only have 1 blanket...I got rid of a couple old ones when I moved and hadn't yet replaced them.
