The West Coast Greyhound Gathering will be held in Solvang, CA, this coming weekend. It's three days set aside where people and their retired racing greyhounds can socialize, go to seminars, shop, and participate in events. One popular event held on Saturday morning is the Solvang Streak. A grassy area within the Solvang elementary school is fenced off, and the greyhounds are allowed to run, either one at a time or in groups (provided they're muzzled), from one end of the enclosed area to the other. The local police clock each hound's speed; the winners of various Streak categories are awarded with racing silks embroidered with the name of the category at the Saturday night buffet dinner at Pea Soup Andersen's.
While the run is not long enough for the hounds to reach their top speed, I'm still amazed to see them go as fast as they do. I'll set my camera to shutter-priority, set my shutter speed at 1/2000 second, ISO at 800 or higher, and then shoot as the hounds pass by. Depending on what model of Nikon DSLR you have, you'd either: (1) turn the exposure mode dial atop the camera to "S", then spin the rear command dial to the shutter speed you want, or (2) on my D300 you'd press the "Mode" button, and while holding it down, spin the rear command dial until "S" appears on the top LCD panel, then release the "Mode" button and spin the rear dial to the desired shutter speed. The camera then picks the appropriate aperture for the correct exposure. I happen to use 1/2000 sec, but if you've never used shutter-priority before, try one shutter speed, shoot a few frames, preview them, then adjust the speed if necessary until you get something you're happy with.
