Sounds like you raised some great kids! I agree with HOLDING THEM ACCOUNTABLE and that is lacking in our society and our parenting. My Daughter calls me the Tiger Dad so at least she's feeling the pressure. I do worry that they are seriously ill equipped if I was being totally honest. Suggesting that you need an above average IQ to ride a F6B sounds a bit elitist to me. I have an average IQ and turn wrenches for a living, and I do just fine on a bike. I have owned my own business most of my life, and make good money.
