It's still in the 90s and even the lake water is warm, although not repulsively so. That means, of course, that summer is still firmly in place. Absolutely not going anywhere. But is that true? Certainly most people around here would like it to be endless, but if you know where to look, there are undeniable signs of an impending change in the seasons. Some of the birds have already begun migrating. There's an entirely new suite of plants, from grasses to wildflowers, starting to lord it over the green and growing world. And then there's the light. It has a new richness, born of a deeper saturation and an autumn enhancement in the red and far red spectrum. This shift only makes its presence known at one time of the year, and while, to summer lovers, this is the season that right now can't be named, it's a season that is, these twilights, in absolutely plain and delicious sight.
