The Motocross Radio website and radio station has been going strongly for a week or so now, and i've spent a little time chatting to the guys, who seem like a great bunch.
They're putting more and more content into the Radio broadcast, and the music they play is great!
Checkout their website at www.motocrossradio.com or their broadcast here
Or drop in to their chatroom here using a java chat, or here using irc.
