Sample instructions: From Ann Arbor, take 94W and take the Baker Rd. Exit 167. Turn right off the ramp onto Baker Rd. Continue for almost 3 miles until you arrive in the town of Dexter at a T in the intersection. Turn left (this is Main Rd). On your right you will see a park with a hexagonal-shaped shelter/platform. Turn right immediately after this park onto Central Street. Follow Central Street which turns into Mast Street after you cross a river. Eventually, the road splits and Mast Street goes left and Daly Rd begins to the right. Take Daly Rd. to the right. You will see several houses on your right and then a lake. Just after the lake, turn right onto Looking Glass Lane.
