Did I mention that there is a map?

Tucked into the back cover of the Special edition and sewn into the Standard edition, there is a map of the trails of Corriganville Regional Park. It also shows the collection locations of the specimens in the book. Also, all the sites of the old movie sets from when the area was a popular movie ranch and location for many cowboy movies and television shows.

It was printed with five polymer plates except...

a couple pieces of type somehow didn't make on to the plates and had to be printed from handset type in interesting arrangements in the bed of the press.
