When making boundaries where there is an impassable area of the field, how do you do it?  Example would be(is) a creek bisecting a field.  In effect it makes two fields, but I want to manage it as one.  Do you just make two exterior boundaries and then make sure they both make it into the profile or drive around until you can't go, pause - drive all the way to the other side, etc... and then make an interior boundary the same way??  Thanks, Ben
