Ah, the long day of pain, but oh, the stories to tell. From Sentinel Dome to Glacier Point around the Panorama Trail to Nevada Falls, down into the valley to discover that it was late afternoon, that hiking back up via Four-Mile Trail wasn't really an option and that there was no bus back up and thus walking through the camp sites to find somebody willing to make a few bucks driving us up (since park staff didn't seem interested in either helping us out or having a summer student get the cab fare).
