Luckily for us sometimes dmatt is not 100% right.
For example yesterday we had an ideal weather for Mt.Whitney hiking.
However it was a surreal experience for me not to see even a single tent at the Trail Camp on Monday morning.
Apparently all people were scared off by the Saturday's and Sunday's weather.
In a hindsight I should have taken Microspikes with me.
In case of a late return switchbacks can have patches of ice.
Are the (potential) patches of ice large enough to need spikes yet? I was up there over Labor Day - and hiking up in the dark there were a few icy spots, but no more than a step's worth long. I'm heading back up the 24/25 and would like to pack my yaktrax if they'll actually be useful (or leave them home if not!)
