With friends while backpacking...
It was pretty cold (-7°C with winds, making the windchill drop to -15°C or so), but fantastic!
Tried to go again in feb 2012 but the weather was too bad, couldn't get there.
"No matter how big a guy might be, Nicky would take him on. You beat Nicky with fists, he comes back with a bat. You beat him with a knife, he comes back with a gun. And you beat him with a gun, you better kill him, because he’ll keep coming back and back until one of you is dead."
