Yow. I found this at the Uncontrolled Airspace blog.
"The pilot of N1312R has a slightly dodgy landing at Alton Bay in NH Feb 10 2007. Alton Bay is actually a sea plane base, but in the winter it freezes over and the operator ploughs a runway."
Slightly dodgy doesn't really cover it. Any runway with ice on it requires some fairly serious concentration, let alone runways that are made of ice.
