Let me know what the two of your plans are-I'm in limbo whether to drive up due to the weather/ice. If microspikes are required I can't get my hands on em.
There are microspikes in the hiking/climbing store right near the road that leads up Whitney Portal in Lone Pine. I am sure folks here can tell you the name of the store. I saw the Katoohlas there last month and the price was the normal $50 range.
