Slightly off topic, but I read this gem in an old Readers Digest:
Some years back, when a survey team came out to the Vermont/New Hampshire border, they were approached by a Vermont native, who asked what they were doing.
They explained that they were readjusting the border and the Vermont resident now lived in New Hampshire.
"Thank God" he replied, "I couldn't take another of them Vermont winters!"
FWIW, I grew up near the western shore of the Red River which marks the boundary between North Dakota and Minnesota. When the Army Corps of Engineers made some channels in the oxbow to speed the flow of the river in the 1930s, it actually took an Act of Congress to recognize the new boundaries. North Dakota gained a few acres of territory overall.
No such act was passed when the Mississippi River changed course and, as a result, there is actually quite a substantial part of Illinois on the Missouri side of the river today as opposed to the reverse. As a result, Kaskaskia, the old Illinois Territorial Capital is on the Missouri side of the river today.
