By whatever route you deem most favorable, aim for the town of North Manchester, Indiana
Main Street in North Manchester is IN 114, which runs east and west.
A couple of miles east of North Manchester, IN 114 intersects with Wabash County Road 300 E. (The landmark is the Chester Township Fire Station which sits at the intersection.) Turn south onto CR 300 E.
Go 1.5 miles on CR 300 E and you will see a green street-style sign that says "Hawkins Lane" on the east side of the road.

Turn in, come back the long lane to the barn lot.
