I don't recall seeing leaf change this way in previous years. As usual, there are some early, stressed changers. There is a flash of red and orange here and there, some yellows with downed leaves (poplar, willow). This part is typical for mid August. What I find unusual is being able to see the underlying colour while the trees are still green. Maybe it's just me?
Anyone thinking of colours jaunts to the countryside this autumn should consider booking now. The bookings for September and October are way up from last year.
