Decent sites for getting a dirt fix?

Youtube always provides a never ending stream of new videos, and the great thing about it is they "recommend" videos to you after they pick up on your interests (have to favorite some videos first). My recommended list is practictly all motocross. There is also a moto section in shredordie.com:

I posted some videos up there of some races at Carnegie too, if you're bored (not too interesting but its local to me and was fun to watch):

And the kiddies:

Another good site (just search for keywords) is streetfire.net:

...they've also got a ton of other great videos of performance cars.

Go to the pro sites for pro speed: http://www.motocross.com/, http://www.supercrossonline.com/multimedia/Article.2008-10-17.5131, There is some stuff around for the Dakar rally also. http://www.dirtrider.net/forums3/showthread.php?t=170134
