Apparently, the was wrong. Today is the first day of Spring, but Nature has been telling us it's coming for weeks now. With temperatures in the 60s and 70s over the past few weeks, buds on the trees, and daffodils already beginning to bloom in the sun, Spring has already sprung.
Also, according to folklore, today you can balance an egg on its end. Check out the video by the Bad Astronomer and try it with the kids, if you can get them to sit still for five minutes in this gorgeous weather.
