is this show cancelled?

I'm on the boards and TV Show sites now to try and find out something. I saw a transcript where JD had done an interview around the time of Tehachape (sp) and he said they wanted to do the next shpw in Alaska.

Edit: I have been searching for... woah! A LONG time now, (3 hours?) and the only thing I am coming up with is Wikipedia having it on their site that the show was cancelled after season 6. I've tried to verify but can't find anything.

according to what Wikipedia say, its been canceled on March 8, 2008.
