Great Idea on the Summit electric blanket.
http://www.summitracing.com/parts/MXI-20013 She will like this. I put a 12V terminal strip under the dash for things like this. I used to ride a motorcycle and have a Widder electric vest and figured I could use it in the car...... That was a few pounds ago and now I cannot zip the damn thing up! I am on a diet now so I should be able to get into it in the not too distant future I hope. At any rate thanks for mentioning the blanket.
