100% agree on slush. There's a right kind of spring slush where you haven't seen the freezing mark for a few days. It's way better than the freeze/unfreeze/freeze/unfreeze stuff. I went to Timberline the morning of the super bowl. Light rain, 50F at the bottom, felt almost like powder (just a bit slower and more tiring). Every slope was open. Very little ice outside of some shaded, north facing patches.
PS: People in the west laugh at this sort of talk
