wow...truely a spirited discussion and brings to mind many thoughts of how i handled things when my kids were younger...of course always a helmet full jeans and jacket and gloves. but i will say this. i started them at young ages sitting in front of me as i went up and down the driveway. now they are 20-14 some met alex at the bash she is 18. ALL..and i mean ALL want me to take them rideing WHENEVER AND HOWEVER and speak frequently of getting thier own bikes and INSISTING daddy teach them how to ride. ..... that my freinds may have been worth all the risks (as they grew older...rideing style aggression increased) as now i have memories and common intrests that sometimes is hard to keep with your children once they turn adults.... life is never predictable but you do still have to live it.
