I hear you on that one. My son is turning 16 this July. He is no boy anymore either. I remember his first MX bike, a 1998 CR80RB at 13 y/o and 150 lbs. Now he is young man turning 16 that weighs 220 lbs at 6 feet tall. Luckily for me he loves hanging out with mom and dad still. We still ride a bunch, but he doesn't like riding his tricked out Banshee in the desert anymore, only the sand dunes. Too many rocks and generally too hot, since we ride the dunes when the weather is cool. They grow up fast and have to get into the real world faster than I thought. Enjoy your time with your kids, don't punish them in ways that keep your family from hanging out together (taking away the dirt bike during family functions), and remember that they may look like grown ups ( 6 feet - 220 lbs at 16) on the outside, but are still just children on the inside.
HAPPY FATHER's DAY you DAD's
