Note to self:
When you need to reset the clock on your stereo in the van and you go out in the driveway to do that, you should not leave the keys in the ignition and in the on position and then get out and lock the doors and go in the house and forget the whole thing until the next day when you try to leave but can't find your keys, only to discover that they're not only IN the van, but the ignition switch has now been on for the past 20 hours or so.
Cause if you do? Your battery will be deader than dead.
But you will be happy that your husband has a battery charger.
