Too many, any time I'm in amazing places with cool people. The standouts:
-Adventure skiing and first descents in Western Greenland
-The first time I really nailed a 55 degree line on skis
-The first Lundy trip and every one since
-Getting the fear on Repentence (WI 5) in the US
-The Crack on Gimmer with a really good mate under a blazing sun
-The Conger and Freeborn Man at the 2003 DWS Fest
