Nice thread. I enjoyed your crowd shots. There are a lot a suburbs that are actually very pretty compared to what you presented, but there are also a lot like those. I guess that's the best some people can afford, and they're probably happy.
It was the old Foley's Department Store (1947), which later became Macy's.
It was where my Grandma took me many times when I was a kid. She bought me an airplane or car model in the toy department every time we would go there. One time, a guy snatched her purse at the front door and took off. The police found her purse but of course the valuables were gone. That was sometime in the 60s when downtown was full of people shopping.
