Standing at the end of Reynolds Street on a brisk Monday morning: look to the right (top photo), straight ahead (above), and to the left (below). There is sufficient wind to make the life ring into a little sail. The teal blue of Lake Michigan is immensely satisfying, no matter which season is at hand.
There must be an infinite number of shades of “blue” in nature!
Your pix sure does make Big blue look “brisk”.
