Missouri and Kentucky share a common border, but there is no road or bridge crossing that border. But there is a ferry.
Montana and South Dakota also share a border, but there is no paved road crossing it. The South Dakota pavement stops about 3 miles from the Montana line, and it's gravel from there on.
The largest US county in land area east of the Mississippi River is Aroostook County, Maine. Aroostook has 6,671 square miles of land and is actually bigger than the largest county in Texas (Brewster).
It is impossible to measure a coastline accurtly because the little jogs and dibbits in the coast, and you measure by units, so any distance less than that unit is ignored if it does not have the same angle as the rest of the coast.
Also when a estuary becomes a river is also a point on contention, which, especially in Maine, where there are many little forges, could greatly effect the length of the Coastline.
so therefore all coastline measurments are estimates.
The state of RhodeIsland shares its name with an actual island in Narragansett Bay. The 37.8-square-mile island is more commonly called Aquidneck Island to distinguish it from the state.
The Red River, on the North Dakota-Minnesota border, is the only major river in the United States that flows north. (The Mackenzie, which is much longer than the Red, flows north in Canada's Northwest Territories...but that's not the United States!)

Floridians might take you to task on that as their longest river flows north.
And while its total path is a big arc, the Tennessee river flows due north once it makes its broad swoop thru northern Alabama. Its course thru both Tennessee and Kentucky before it empties into the Ohio after leaving Alabama is due north.
I'm not going to check, but I think it is true that the Red River of the North is the longest river whose source is south of its mouth, and therefore flows north. And it is much longer than the St. John's. That is how one defines a river flowing North. Even the Mississippi, at a few places, flows north. The source of the Clinch River, and hence the Tennessee is slightly further north than the mouth of the Tennessee, so even that flows more south than north, although it flows north at is most prominent parts.
As for the statement that it is the "only major river" that flows north, it depends on how you define major.

The Pend_Oreille_River in Idaho/Washington flows north. Not as long as The Red River, but has a larger flow.
Just checked, the Clark fork River Idaho/Montana also flows north and ihas a bigger flow then The Red river.
