Watching this 1987 video of two Radio Shacks (one with Madonna music in the background) makes it clear that 30 years can be a long, long time ago. Prancing Skiltaire (the person who uploaded this video) said, "This was shot in Garden Grove, CA and Buena Park Mall, CA. The person who recorded was an employee working with a regional manager who was inspecting under performing Radio Shacks they were going to renovate." I was fascinated for all 15 minutes of this spellbinding video.
