Guess I am a little confused. Walter Reed was completely and I do mean completely updated and remodeled in the late 1970s. Basically gutted and tore down and rebuilt all except the central front facade. I know I was there.
Just for your info the 70's was 30 years ago.
30 years is a long time for a hospital to not be renovated or updated, especially with the advances in medicine in the past 20 years or so....
