Over the course of nearly 30 years, park enthusiasts Margaret and Edward Gehrke
from Lincoln, Nebraska, made pilgrimages to national parks across the country.
As seen in this clip from Ken Burns's film, THE NATIONAL PARKS: AMERICA'S BEST
IDEA, Margaret would record the start of every trip as "the day of days" in her
journal. Edward would bring along his Kodak camera, snapping pictures Margaret
would later carefully place in photo albums to commemorate their adventures.
