Fall is a great time to follow some kids into the woods - let them do what they want (be sure to keep the parents way back and quiet, as they'll fret over the danger to the cleanliness of the clothes, etc...) - that includes jumping into piles of leaves, throwing them around, or just plain showing them the camera!
You'll need to be quick on the shutter, and willing to shoot way too many frames, allowing for quite a few to be out-of-focus or motion-blurred, in order to have some great choice to pick from... Keep the camera is aperture-priority, with the lens set at its widest (smallest number), in order to get the highest shutter speed - kids don't hold still!!! Shoot RAW, to allow yourself the luxury to fix exposure and white balance later, on your monitor.
