Lower Main is easily visible from the main lodge and associated buildings, as well as the Nob Hill chair, so it can increase the intensity of the run.
It often hosts races as well.
Other than that, it's a very wide run, with a consistently steep pitch, and often excellent snow conditions.
On the steeper end of blue runs.
The trees on skiers right can be fun to dip in and out of, with a good sized rock drop at the bottom right which is droppable in good conditions.
Check the landing for rocks first - low snow conditions can make it a trickier landing.
Make sure to carry speed at the end if aiming for Grand View Express or Tahoe King chairs.
