I should have qualified that KOP was the largest mall I knew of which is why I called it out. I did forget about Springfield mall which is still alive I assume. https://en.wikipedia.org/wiki/Promenade_at_Granite_Run is turning into a classic shopping center which was my closest mall growing up. In Pittsburgh https://en.wikipedia.org/wiki/Century_III_Mall is getting turn down, Ross Park Mall is declining and Robinson Town Center was half empty the last time I was there ~5 years ago. I can't speak to malls I didn't frequent.

Although "still open" isn't exactly saying much either on your end - how many stores are empty? Are they on the decline?
