Please note
, our address does not place properly in most navigation software because of the way Highway 40 is numbered.  Navigation systems will put us in a wrong location. We recommend putting in the intersection into your nav unit and you will find us easily:  we are just west of the intersection of Sterling Ave. & US 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
