I have an overnight pass to camp on Mt. Whitney Friday 8/26 - Sunday 8/29 (3 nights and 4 days). The parking pass I will receive will cover me for trailhead parking those four days, correct? But....there is no guarantee I will have a parking space either, right? I'm scheduled to camp at Whitney Portal Campground on Thursday 8/25, the night before, but I'll have to vacate that space on Friday. This is a difficult trip for which to plan. I wish I could think my logistics were done and just focus on conditioning and acclimating. Help!!!
