 Going West out of Spencer on State Road 46 you will run right into Vandalia.  and  I 
believe that the old Methodist Church which the cemetery is by is on the left 
hand side of the road.  There is a turn off to go to Patricksburg on the left 
as well [SR246] and I think it's very close to that turnoff if I remember 
correctly.
