In a "For Sale" lot, looks like an abandoned house. Huge patches of knotweed (I think Japanese knotweed from a distance). Just want to make sure that you know of it. Located off of east side of Cornelius Pass Road, heading north of Hwy 26, between NE Wagon Drive and NW Rock Creek Blvd, just south of Christian Center grassy field. You can't miss these big plants!
