What did the author find sad about her visit to the Schofield Army Barracks in Honolulu as noted in the nonfiction book, The White Album?

Schofield Army Barracks in Honolulu is a location that Didion visits whilst on her holidays to Hawaii, in an attempt to move closer to one of her favorite authors who wrote a memoir of the army about his time at Schofield. Didion finds that little has changed in Schofield, and reflects that it is now sad that very few people in Schofield seem to remember or even grasp the meaning of the novel 'From Here To Eternity.'
