I understand what you are talking about because the first time entering these spaces always holds a sense of wonder and discovery. Just like exploring the backstreets of some medieval city but since I generally shop alone and with purpose I am always frustrated by the process of exiting.
I would say that we never felt “trapped” by Horton’s layout. There were plenty of clearly-marked exits around the perimeter. But the maze features were remarkable and unique for us.
There were bridge walkways with an incline of half a level. There were asymmetrical stairways. The perimeter of stores was not square. There were many levels and elevators. There were no particular “anchor stores” like the big department stores, although the multiplex theater was a focal point.
Elements that kept us inside included food and the aroma of food. Just thinking back to 1989 in Horton, I can practically smell the warm pretzels, cinnamon rolls, and candy stores. There were benches and places to sit. There were sculptures and bold colors and the Jessop’s Clock. Santa Claus and his elves every Christmas. We were in the heart of downtown, but crime was unheard-of and mall rats did not bother us. It was a place to walk around and share family experiences. Perhaps we were the mall rats.
