Hogwarts-ish school in the US?

[Sea Change]

I wonder just how good apparition and portkeys are in terms of how far
you could go with them, and how easily and safely they can be
established.  If a portkey can take one clean across the UK, then
there's no reason anyone who had the means to pay for education
wouldn't just portkey their children across the briny.  Similarly, the
states on the east coast are awfully tiny, so there isn't much need
for each state to have one.  Another reason for them to be rarer than
states is that the schools need to be hidden.  The establishment of
new schools would be due to political barriers, more than anything.

There's no particular reason the US should have won the Battle of New
Orleans, and New Orleans has a history of being
traded/conquered/occupied by several foreign powers, including France
and Spain.  Whoever started this particular school of magic probably
wasn't very nationalistic, and one shouldn't expect that now, given
how long wizards tend to live. This is the school where you'd be more
likely to find african-american students.  Probably for many years,
voodoun was repressed in magic schools, just like in mundanity. This
school is probably not in New Orleans proper, but in the Atchafalaya
region, near the Yazoo.  It's not accidental the US Army Corps of
Engineers has invested such a huge amount of money and manpower to
keep the Mississippi from jumping its banks with the Atchafalaya Project.

The huge immigration of and discrimination against the Irish resulted
in Notre Dame and the Mayo clinic, so there's probably a 'Newgrange
Barrow' druidical school near Chicago, perhaps in the isolated
non-contiguous part of Wisconsin.

The Civil War resulted in a mundane blockade of the CSA, and the UK
(sorta) honored it.  I would expect a school on a barrier island
(because they are known to be evanescent) somewhere off South Carolina
and Georgia.   Some pretty severe race and class distinction has been
around this region for years, so this school probably has an unsavory
reputation.  Wizard robes-Grand High Wizard, you decide.

The Navajo and the Sioux are the two continental US tribes who
resisted being conquered the longest.  As far as native schools, I
agree with the Black Hills assessment, and also suppose another near
Shiprock or Sacred Mountain.  These schools are likely underground or
look like huge rock formations.  Many Inuit got a better deal from the
US by being incorporated instead of reserved, so perhaps a third,
arctic one, somewhere near Juneau or Great Slave Lake.

Yellowstone is an obvious place of power and interestingly enough was
the first national park.  Even now, they are trying to get
snowmobilers out of the park, to reduce Muggle presence. This is the
school where I would expect the most Scandinavian/German history, but
predominantly a Mormon influence.

The other early national park, Yosemite, is in California.  It's not
so close to San Francisco, but *is* close to the gold and therefore
it's a good bulwark against Goblins.  This school is probably
something of a fortress and the sheerness of Half-Dome is not
accidental.  It's something of a mystery why San Francisco got its
water from the equally beautiful and similarly close Hetch-Hetchy
system intead of Yosemite.  This 'Ansel Adams' school now has a nice
reservoir nearby to limit neigbors, and unexpected muggle deaths can
be blamed on climbing accidents.  The road by the Merced River still
is known to drop rocks and kill people, and several other access roads
are often snowed in for long periods.  This proximity explains not
only the wierdness in SF, but also the gambling/prostitution in Las
Vegas (consistent with having a garrison nearby). 

The last school is probably the only nationalistic one, started by
FDR, in the Tennessee Valley Project.
