Found one last spot that seemed like a great site. Ended up being next to a group that cramped 20+ people on one site, drinking and yelling until two with a huge lantern that lit up everything around it. It was like I was camping in the middle of the day at a frat house. No sign of any ranger to enforce the so called "quiet hours" of 11PM. Packed up at 5AM and went to Yosemite Creek instead.
