Please note, our address sometimes does not place properly in some navigation software because of the way Highway 40 is numbered. Some navigation systems will put us in a wrong location. We recommend putting in the nearest intersection into your nav unit and you will find us easily: we are just west of the intersection of Sterling Ave. & Highway 40, on highway 40, just down the hill from Quick Trip and right next to V’s Italian Restaurant. We are on the south side of Highway 40.
