I think sometimes I'm my own worst enemy. For some reason, I like to shoot at a lower shutter speed, since I'm so afraid I won't get what I want in focus, shoot at a slower shutter speed for a greater depth of field, and that way I'll get what I want in focus.
Here's a perfect example of one of my nephews from last winter. I'm shooting at 350 on the shutter speed and probably should of had it a bit higher, since he was clippin' along pretty good.

Edit...........my nepew in pretty good focus, with the snow flying (blurred) makes for a pretty good picture (at least I think since it shows a sense of speed), however, shooting at 350, the only thing that save me was the Pentax stabilation.............otherwise, I'm thinking my nephew would of been blurred as well to some extent.
