Cross Bering Strait on foot, get arrested when you hit Russia

And you thought the southwestern US had border problems: Dimitry Kieffer of Alaska and Karl Bushby of the UK were detained by Russian authorities after the two completed a rare, dangerous crossing by foot of a frozen 56-mile stretch of the Bering Strait:

The two were arrested in Chukotka province for failing to register with the authorities, Andrei Orlov, spokesman for the Federal Security Service's (FSB) northeastern border guard division, said on NTV television. All visitors are required to register with police within three days of their arrival in Russia, even if they have visas.
