If you’re coming from Northfield on Hwy 3 (heading south), go 1.5 miles (from the intersection of highways 3 and 19) till you see the Perkins restaurant, and then take the first left (east) on Heritage Drive. There’s a car dealership on the right (west) side of the Highway. (If you see Target, you’ve gone too far.)
If you’re coming from the south, take a right (east) at the first intersection past Target.
Head east on Heritage Drive for a couple of blocks. We’re the second unit of a green and red fourplex townhouse at the intersection of Heritage and Valley Drive.
Below is my marked-up version of the map. Follow the blue!
