WTF, Richard Rhyner. I was a single, working mom and wasn't always there to "greet and look after" my son when he came home from school and, OMG, he even played video games (imagine!), and guess what? He was just awarded a PhD fellowship at Stanford. So tell me again how "Children of working mom (sic) don't fare as well at all," okay? 

P.S. You go, Kikkan! You are a beautiful, strong and awesome woman, and you are going to totally rock both motherhood and the ski circuit.
