Thank you, everyone, for your responses! I am going to have my mountaineering boots in my car, so if I need them, I can put them on, should have a pretty good idea of weather conditions the afternoon prior.
We are camping at Whitney Portal the night of. Does anyone know if there is phone signal up at Whitney Portal to check the weather conditions/forecast before heading out?
With Verizon Wireless I can get a 4G signal at the last bend in the road before Whitney Portal, but nothing beyond it. That is, I have parked at the portal and walked back down the road and stood on the other side of the guard rail to pick-up a signal. I've had no signal at the portal campground.
