Today is the day when we all get 12 hours of daylight and 12 hours of night. After today, those of us here in the northern hemisphere will have shorter and shorter days until the solstice in December, the shortest day.
This weekend we will celebrate the equinox as we normally do with fire (we have one of those outside fireplace things), food and beer. Several of our new friends will come over to enjoy piles of food. Hopefully we won't get rained on!
