At this intersection, take a sharp left onto Plummer Spring Rd. Go 0.2 miles, cross a small overpass that has guardrail on both sides of the road, then turn left into the first driveway at 443 Middle Street.

At the set of lights, go straight (you are crossing over Low St); you are now on Hale St. At the end of Hale there is a stop sign. In front of you the road will fork in a Y. Stay to the Right side of the Y (it’s at about 1 o’clock). It is marked Plummer Spring Rd. You will soon see the Artichoke reservoir on your left, then you will drive over a little overpass with guardrail on both sides of the road. We are the first driveway on the LEFT after this overpass. It is a hilly, winding driveway with #443 and the letters "IMCN" on mailbox. You cannot see the building from the road. At top of driveway there is parking lot on the left.
