You can never be sure just how much longer Summer will hang around. I take every opportunity to photograph the remaining flowers. This colorful scene may be quite different in just a few weeks. Perhaps one of the best ways I've heard this change of season described is in a John Mayer song.
"When autumn comes, it doesnt ask. It just walks in, where it left you last. And you never know, when it starts
Until there's fog inside the glass around your summer heart."
