On the scenic train ride back to Rockaway Beach from Giribaldi, we saw the Coast Guard operating in the bay. It appeared that they were practicing helicopter ocean rescues. I kept shooting as the train went on Northward. I was using my telephoto lens from the shaky train. I had to keep the shutter speed pretty high to avoid blurring from camera shake, hence the nearly frozen rotor blades. Here is my favorite shot. It's from a ways out and I did get some much closer shots that I'll share on Flickr. I like this one with the rocks in the foreground on the left.
