I've learned many lessons over the short course on my photographic history, but maybe the most important lesson I've learned is that you can't take a picture if you don't have your camera.
I was taking pictures of windsurfers in Hood River for a Weekly Assignment project that I was working through and in the course of waiting for the next wave of surfers to pass by, I was watching the beach goers with their dogs.
When a new dog made it's way on the scene it was almost immediate that the rest forgot what they were doing and came straight over to "greet" the new arrival.
I was already set for shooting action with the wind surfers, so as the scrum appeared I was able to get a picture of the pack. It was a comical scene, and one that I would have missed if I didn't have my camera ready.
