Are you staying in Durango for your Wolf Creek trip (90+ minutes away) or are you staying in Pagosa Springs. If you are staying in Durango proper, it's a college town. Plenty of Bars there to get your drink on. Some great places in the downtown area and a very young crowd. I would also recommend hitting Purgatory (Durango Mountain) as it is like 10 minutes from Downtown Durango.
If you are staying in Pagosa there are a few places. The Durango Brewery comes to mind. They make some good beer there. There is also a nice little Mexican food place on the main drag and a decent bar that I can't think of the name of. It's a little more local and redneck there, but not lumberjacks. More like Ranchers...
