A quiet day, overcast and cooler than recently. Not many people on the heath; lots of people are probably on holiday or back at work after the summer. Lots of dogs as usual, including some dog walkers. Green parakeets screech in the trees and whip through the air overhead. Footsteps crunch on the gravel as we proceed up the path to Kenwood Gate. Yellow is everywhere, the paper-dry grass contrasting with the deep greens of the trees.
