I'm heading up on Friday and will take some photos and post my trip here. I will probably start around midnight from the portal parking lot if the switchbacks have ice/snow on them...this way I can see the switchbacks clearly with the sunrise around 5:30. I may start late Thursday night if the snow has cleared/melted by then. I'll check back here before I head up to see if there are any updates on the switchbacks.
Thanks for the update about your trip.
Nate
