Bitterroot is a really fun run because it has a good consistent pitch.
its not that steep, but you can practice making symetrical turns on it.
It gets groomed often and hardly ever has moguls on it, with the exception being the lowest section early in the season when the snow is low.
Dipping in to the trees on the skier's right side is a good idea on a powder day.
The trees are nicely spaced, and don't get skied that often.
Bitterroot gets sun affected later in the year, which makes for great skiing.
