Very interesting to see some of the rain clouds develop and move toward you. Even though you can still see blue sky, the rain clouds move right along. This one was heading right towards me and you can see the ripples on the water as the wind all of a sudden picked up and started the wave action. At this point, it was time to head back to the car and stay dry.
This is a neatly timed shot - particularly like the moving ripples you caught following the direction of the cloud movement. Definitely was time to head for the car!
