Cat Fight!

After finishing a practice run and getting out of her car, Danica Patrick quickly walked to where Milka Duno, the only other woman racing there this weekend, was pitted and argued with the less experienced driver about getting in her way several times during the practice.

The altercation lasted only about a minute, but witnesses said it grew heated and that Duno flung a towel in Patrick's direction at one point as the two exchanged words. Patrick eventually walked away.
