There is something magical about that first, crystalline blue sky that heralds the coming of Fall. You can feel a tangible change in the air, but you’re not quite sure what it is. You only know you’re overwhelmed by the beauty of the day, and the crisp, wondrous feeling of life that surges to the forefront when it dawns. You step a little lighter, look up to feel the sun on your face more, smile broadly at the folks going by without exception. You can taste living. September 11, 2001 was such a glorious day. From New York City to Pensacola, Florida, and Cranbury, New Jersey.
