Innberga

Þjóðulfr (and) Búi, they raised this stone in memory of Farulfr, their father. He met his end in the east in Garðar (Russia).

This rune stone is standing next to a small creek, but there's no mention about bridgebuliding, which is very common when stones are raised in places like that. I suppose that Farulfr travelled on the Russian rivers, and raising this memorial next to a creek would be a fine way to visualize his final trip.
