Liftline is an intermediate trail that runs underneath the Sun Bowl Quad and is a good escape from Middle Wingding if you want. To get to it go to the summit of the mountain and ski down either Upper Wingding to Liftline or ski Upper Williamson and Crossover to get to it. It is a relitivley straight trail so you can get some good speed on it. It isn't all that steep and it does offer the lift towers to avoid. There are many times that it has moguls on it. I'm not sure if they are intentionally built or if the groomers just leave the trial like this. If you want a bump run in the Bowl here is your chance.
