4. Who is this guy, and what type of vehicle is that thing?

Johnny Cash worked at Pontiac Car Assembly for a short period of time. It is believed to be the inspiration for his song “One Piece At a Time (YouTube link) where he takes home a different part each day and tries to build a car!

Contemporary folks remember Cash sitting on the front porch of the house where he rented a room, playing his guitar. The house remains, just north of Howard Street on Saginaw.
