For me I think it would be the Burlington County Mall. I remembered going there once as a kid. A decade later, I saw a picture of how abandoned it was, and that led me down a rabbit hole into seeing how other malls are doing.
How did you begin?
The mall I grew up with. Westminster Mall in Colorado. I watched that shit die. Unfortunately, this was before dead malls became a popular thing to marvel at. Ultimately, it was demolished 10years ago. I just remember it slowly dying as some wings became completely empty.
The only remnants I can find on it is this post from the Dead Mall Enthusiasts Facebook group.
