Also too, it's not just World Car-Free Day, it's the autumnal equinox. Today (ignoring atmospheric refraction and the fact that sunrise/sunset are defined as the moments when the last/first bits of the sun's limbs cross the horizon) day and night are equal lengths. For the next three months, nights will get longer and days shorter. Then ever so slowly, the trend will reverse.
At 70 degrees and partly cloudy, this seems like a very auspicious day for the first day of fall. I'm loving it.
