Another blogger posted about her Zach Roloff sighting.
Matt and Zach were on a road trip through a few states. This one was in Ogden, Utah. According to the blogger, Matt and Zach were picking up a vehicle from a custom auto shop...
The blogger had a soccer game at the indoor place across the street from the auto shop, when Zach walked in. The team invited him to play so Zach played.
They have video of Zach playing in the soccer game that was taken on a phone
They have some nice pics of Zach here:
