Great stories, all.
My son already wants to get the bike fixed. We'll be back on the trail in no time.
My wife told me that my son only kept a stiff upper-lip when I was around. She said he was pretty upset when I wasn't looking. I'm actually quite glad because that means 1) riding is something he really wants to do and 2) he learned a valuable lesson that didn't cost more than a few parts and a lost day of riding.
