I guess the icecaps are melting and moving to Vail.
From Operation Sunshine - under the North Pole ( Re USS Nautilus ) : " On 19 June she entered the Chukchi Sea, but was turned back by deep draft ice in those shallow waters."
That was 1958. This year these waters are ice free in mid-May, and have been so at this season in recent years. The North Pole came close to melting in the summer of 2007, and the trend is definitely that way, even if there are reprieves.
Just sayin'
