We actually got lost on our way to Union City. We exited at Dumbarton Rd which led us to a wilderness. It felt like we were going up to Baguio but the roads were well paved and the winding roads were complete with street signs, emergency phone boxes, etc.
As soon as we reached Fremont/ Union City boundary, we ended-up in a street lined with Victorian homes.
I wish I was able to take more pictures. They’re so nice.
