I do believe, almost 100%, that you have there a wolf spider. They're fairly big and don't spin webs. Instead they generally live outside, and eat larger bugs, and actually HUNT them at night. I once had one in my old swing set when I was a kid. I jumped off the set, turned around, and watched it crawl out of the top pole. Very, very scary. Here's a clear picture of a wolf spider....is this what you have?

Edit: Nevermind, Imageshack showed me the picture bigger this time, and yes what you have there is a wold spider. *shudders*
