Check with your insurance company in sweden. They should cover your insurance. My travel insurance company here in Norway will cover up to 10 000 000 Norwegian Kroners(aprox. 1.5 million USD) in Medical Insurance. Pretty dope.
And getting into the country, call up the nearest US embassy in Sweden, they'll hook you up with a visa. I'm going to the US this winter aswell, LA, Colorado, Utah, Mammoth and SF. But I'm an American citizen, so I'm hooked up. haha
BTW. It wasn't only the war on terror that fucked up the economy. Most of It was banks who lent out way too much money, over a long period of time to people who couldn't pay back their loans...
