This is one reason I like to show up early to work. To, you know, clean up. Going home is another story. Not very sexy showing up with snot on your face/shoulder/thigh/shoe,etc. My wife is a skier and can blow rockets with the best of em. Her only advice was to practice... but not around her.
I will go forth with the advice of this thread tonight!
Chilly weather means lots opportunities to blow.
