Don't be so hard on yourself OLD-N-SLOW. I would bet just about everyone of us dads, and even moms, have pushed our kids to where they are not having fun riding. I know I've done it:( I just have to keep reminding myself that it is their time now, not mine. But I can honestly say, that I can just sit there and watch my son ride, with a grin from ear to ear. The best part about the young when watching them ride, is when they learn to do something new (like their first wheelie, jump etc) for the first time, and then having them come over to ask you if you saw it, and how awsome it felt, with a big ear to ear grin themselves. I know I can sit there for hours watching my boy ride. So everyone just remember. It's there time. Not ours.:D
