In 2002 I was working in Washington, DC for the Recreational Trails Program housed in the Federal Highway Administration and administered by Christopher Douwes. I was on a national team developing a new trail training program. One of our meetings was at Grand Canyon National Park. Sandra came along on the trip. While I was attending the training meetings she explored the Park. There was a cancellation and she was able to hike down into the Canyon and stay overnight at Phantom Ranch and hike out the next day.
