Yes, thank you for the reminder.  I need to do the same for a couple of other new townships I drew.  I had a bad experience with doing coastlines elsewhere before, so I am being extra cautious not to make Lake Erie disappear. LOL. 

While I have you attention, I also have trouble closing the relations on Monroe, Pierpont, and Richmond townships along the Pennsylvania state line.  I can't seem to split the state line and county line relationships properly to close off the eastern edge of those townships.
