One day last summer in Yosemite the NPS collected footage from 30 people and folded it into one video. “How long does it take to see this park?” Now the answer is 14:53 seconds. The day includes time with a chatty ranger on horseback, a couple hang gliders into cluby music, a postmaster from Long Island, and a walk up the chains on Half Dome. If you’re not familiar with Yosemite Nature Notes, you have a lot of great park footage to catch up on.
