The beam made its way to the Bay Area this week via I-580, escorted by a law enforcement motorcade. It's a physical artifact of the Twin Towers — the kind of object that shows up in museums and memorial sites around the country. The Pleasanton display puts it inside the fair's broader footprint, so you'd be seeing it alongside the usual livestock competitions, carnival rides, and fair food.

Practical note: Parking at the fairgrounds gets congested on weekends, especially afternoons. If you're driving, get there before noon or plan to walk from the BART shuttle drop-off rather than circling the lots.

If you've got two hours: see the beam, get a corn dog, find the livestock barn. That's the Alameda County Fair in its compressed form.
