I like taking photos of people. Skateboard park, carnival, festivals, zoo, horse stable. It works better if you have a long lens, so you can get candids. Of course, if you're going to use the photos for anything other than your own enjoyment, you will need permission. Sometimes a non-profit would like the photos you take, and it gives you sort of an "in". I take photos of all of our school events, baseball games, then I share them with the parents on snapfish.
