Summers End:

On September 22, 2009, the Autumn Equinox will signal the beginning of Fall. It is the point where there are exactly 12 hours of daylight and 12 hours of darkness at the equator. Daylight hours dwindle until Winter Solstice, the shortest day of the year and the start of winter.
People celebrate with fall and harvest festivals as the summer season comes to a close bringing with it a long winter. Getting there is half the fun. Drive through mountain canyons ablaze in fall color. Enjoy!
