My dad and stepmom Debbie were at the Brooks and Dunn concert tonight at the DTE Energy Music Theatre so I was flying solo while teaching our 20/20 Vision Summer Workshop that we hold every Thursday in Ludington. Just as I was pointing out the two red streaks in the water from the reflection of the clouds, a sailboat passed near by. F2.8 at 1/250, ISO 640, 18-50 mm lens at 18 mm
