Signs of Fall! August 8th?

I was walking the dog this morning and I saw some leaves turning yellow. The fireweed has finished blooming and one of them had turned to cotton. The grass has started to change color, and two nights ago I heard cranes flying past the house. The Tanana Valley Fair started this weekend. Fall is coming and the plants are beginning the preperation for winter. We are losing almost 7 minutes a day of daylight.
