Happy 100th, National Park Service

For its 100th anniversary, the U.S. National Park Service has erected a handsome if glitchy centennial web portal. Readers can delve into: 

• Stories of individual parks (Find Your Park)
• Future plans (Building on Success) 
• Visionary Leaders (such as environmentalist Marjory Stoneman Douglas, shown above with a feline friend; Douglas's book, The Everglades: River of Grass, published in 1947, describes "the natural treasure she fought so hard to protect").
• and a call to action (Get Involved); this is always a good idea, especially for a perennially underfunded institution such as NPS

Unfortunately the centennial page's back button seems to lead to dead-end error messages. And NPS would benefit from a clear link to a separate batch of wonderful organizational stories. Last but not least, why no Timeline? Maybe it's in there, but we couldn't find it. Business anniversary tip: Honor Commandment 7 of our 10 Commandments of About Us pages, namely Keep Navigation Easy.
