I am on the "Left Coast", never been to Walter Reed. I have had the occasion to utilize the VA facilities near here (Pettus Memorial) in Loma Linda, California. Those facilities were quite impressive, immaculate I might state. Using that experience I simply cannot imagine Walter Reed in the condition reported.
I'm sure the lefty reporters made it sound as awful as possible, but I've seen military medical facilities that were every bit that bad. I also, whether INCONUS, OCONUS, on land or at sea, never worked in a facility that didn't have roaches.
I've only seen the outside of the VA hospital near me, and it looks very nice.
