Evenings Darken Earlier But Roses Still Glowing

All of a sudden it seems like the evenings are darker earlier! As I walk home there have been some spectacular sunsets but my cell phone camera doesn't take sky shots very well. So all I could do was to capture the last of the sun's glow on my roses in the garden. Even though it's 90 degrees this evening, winter is approaching very quietly and stealthily if you just take note of the little signs. Birds practicing formation flights, trees beginning to tinge orange, some bees dead from the sudden cold snap the other day, neighbors taking air conditioner boxes out of their windows, people talking about Halloween and Christmas, wondering when the clocks fall back an hour or when they will stop street cleaning so we don't have to move our parked cars. What other signs are there? .
