Durango shuttle

Hey this is to all you T-Ride and Purgatory skiers.  I'm from Phoenix and since T-Ride and Durango are closest I'm gonna buy a season pass to one of them.  The problem is that I don't drive, to solve this, I found out that there is a greyhound bus that leaves daily for Durango.  I would rather buy the season pass at Telluride, one cause its cheaper and two cause I think its better skiing, my question is this:  is there a shuttle or bus that leaves from Durango going to and from Telluride that I could grab a ride on?  If so, is it free, or how much is it?  Or if you could just point me to a website.  Thanks.
