Six-Years Ago (10-August-2010) — Utah

Gone to See America August 2010 Road Trip. Day 10: Great Basin National Park, Nevada to Park City, Utah.

After a long day driving, I arrived in Park City. It was off season, and the Marriott Hotel I was staying at upgraded me to a room with two balconies and more square feet than my house. I was able to set up a camera on each balcony to do night sky star trails. One camera looking north and up to Polaris, the other looking east.
