    BD has the best idea, it shouldn't take more than a couple of minutes to pull the plugs. If anything does start to freeze, it'll have an outlet.

    Otherwise, AJ's idea will work too.

    I second putting a 100 watt work light in the engine bay for the next two nights. Just to be on the safe side...I'm not sure how far north you are.

    I did the same and draped an old movers pad over the top of the engine.

    I place an outdoor thermometer up by the alternator, the next morning it read 57 degrees when the outside temp was 29 degrees.

    Drop light with 1oo watt bulb FTW

    hmm, i store mine in my garage which is semi-heated back in tandem area. I may take some measurements & see what the difference in temps are.

    if its in the driveway, hook up the muffs, run the water, start it up for 5 minutes
    the residual heat in the motor will ward off any chance for the night.
    plus you will feel all warm n fuzzy inside knowing your baby is outside nice and warm!!

    Light bulbs are great, but not when the neighbor hood kid or dog moves the cord and that light is now resting on something that might melt /or catch fire

    most outdoor cola machines have a 100 watt light turned on inside them during the cold months to kepp the soda from freezing, quite amazing how much heat 100watts is in a small closed area, but I would put one on both side of motors
