I would like to hear from anyone that has done the switchbacks in the last couple of days as to how much snow still covers them. I just purchased some microspikes today figuring they would be useful over snow covered sections, but then I read a post which says they saw plenty of people going up the switchbacks with just treking poles. Thus, I hate to spend money where not neccessary so would love to hear from someone on the conditon of the switchbacks and their opinion is mircospikes might come in handy. We are starting on the trail next Monday,July 11th, so conditions might again change rapidly from here.
