Replying to Stretching

So I've heard all kinds of conflicting information as to what to do in order to properly prepare for skiing/any physical activity. I was wondering in part because I just might win most inflexible contest of the year, I mean my hands don't get within a foot of the ground when I stretch (yes, I measured) so it would be beneficial for me to learn how to stretch to not only gain flexibility, but to prevent injury on the mountain.

Spark Notes: What do you guys do to stretch that works for you that gains flexibility and possibly injury?
