It might still feel like summer with temperatures in the '80s, but it's hard to ignore those crunchy amber Aspen leaves accumulating beneath our feet, or the plump Gala apples brightening up waning famers' market stands. As the sounds, tastes and colors of fall gradually hit Denver, it is time to revel in the annual harvest our town has produced. And what better way to rejoice than with a festival honoring the fall equinox, the time when day and night are nearly equal in duration and summer is officially over, according to the Old Farmer's Almanac, and sometimes called the Pagan Thanksgiving in magical communities. Shift into the new season with one of these Autumnal Equinox events.
