Go and attend an event in your area. Photograph the action and the people. Ask people for permission to be photographed. Most people grant it to you. Have a lot of fun with this exercise.
David and I attended the Celtic Faire in Sonora, CA. The jousting was one of the highlights. I positioned my self in a good spot and picked a fast (1/4000 sec) shutter speed to freeze the action. This is what I got right after the two knight collided. Enjoy and keep on photographing!
