Thanks Jeff.
We lucked out and got the last spot at Little Round Valley! We lucked out the ranger on duty was still in the office when we arrived Friday, and she got us all set up. Great camp site to set up for an early morning summit.
I did think it was odd that despite the reservation system for permits, through the office, they still leave self-serve permits outside the office. Meaning even if all sites were full, someone could still fill out a valid permit for an overbooked site, without knowing it was full.
Either way, great camping, and great hike.
