The crew redid two houses in my area last year. House #1 was the first one they completely demolished and rebuilt from scratch. I showed up to watch the revealing (and Ty of course), and was surprised to find myself on TV a couple of months later in a closeup of the crowd outside the house.
Trading Spaces also came into town last year. Two neighbors of a coworker of mine were getting their rooms remodeled for the second season premiere, and we sat on my friend’s porch watching Paige, Amy Wynn, and a bunch of workers passing back and forth all afternoon/night. It was kind of surreal!
