No, I'm not concerned. I only use them when it's cold and foggy. Or cold and snowy. If it becomes an issue, I'll deal with it then.
In other news... I just loaded up the family and drove out to Idaho over the course of three days.
Covered 1,623 miles and burned 42.31 gallons of gas. That's 38.36 mpg.
Not bad considering the humongimistic MOUNTAINS that they grow out here. Gosh, I miss the flatlands of Indiana!
Hopefully I can repeat this feat on the way home in a week and a half.
