Travelers driving the backroads north of Gresham, Oregon, often slow down when they spot it: a strange, skinny tower rising about fifteen feet high beside a quiet country driveway. It has beige siding, a small pitched roof, and a glass panel facing the gravel lane. It isn’t a mailbox, birdhouse, or deer feeder. Curious drivers sometimes pull over to stare, their minds spinning with guesses. But locals already know what it is — a “driveway periscope,” a clever, homemade device that solves a real problem with old-fashioned ingenuity.
