Location

Across the street (Fischer's Mill Rd.) from the Redland Grange Hall is a gravel driveway into Matton Utilities' equipment storage lot. On the right side of the driveway, near the entrance is a large (40x30?) patch of Japanese Knotweed. Another smaller patch is further in, also on the right, in a pile of logs.
