Given that places like Jackson are usually a bit more reliable for mid winter conditions in February than mid March, I am opting for a pre Gathering trip to Sun Valley, then over to Jackson, down to Aspen and then arrive at the Gathering via I-70 to southern Utah from Aspen.
Post Gathering, I might stop in at Castle and/or Sunshine Village and Lake Louise on the way home or I might wait until late April for SSV and LL.
What a difficult life you have; I feel empathy for your plight.
