I got in the car this morning to find the INSIDE of the windows coated in ice. It took me 20 minutes to be able to get out of the driveway. I was just about to search for possible causes when my wife called on the cell to complain that her car had ice on the inside of the windows this morning. All of the sudden it hit me... we took both cars to the Lake this w/e and I loaded up both with wood to carry home and have yet to completely unload it because of the bad weather. The moisture from the wood caused the ice. DON'T LEAVE FIREWOOD IN YOUR CAR OVERNIGHT.
