Full Moon In Buena Vista, Colorado The summer season is winding up in Colorado and evenings have become much cooler. The traditional calendar is wrong; August 21 is the start of the fall season in Colorado's high country. (October 21 is the start of winter.) In a few weeks the colors of leaves will begin changing in the mountains. Very exciting! Above is last evening's video of the full moon. I do a full 360 degree rotation to show you the scenery. :) -Steve (August 13, 2011) ColoradoGuy.com on Facebook Home
