I haven't fallen due to kids, but I came close. A couple of months ago, I was riding one way on a mup, and a group of kids were on the other side moving slowly toward me. I slowed and thought it looked safe, then one kid took off on his scooter and came to my side of the trail while looking at, and talking to his friends and a collision became a real possibility. I said calmly, but loudly, "Watch where you're going!" While doing this, I prepared to swerve off the trail if needed and he glared at me like I was some idiotic control freak.

I hope you heal quickly... and a bright side note. No matter how many crashes you will have in your lifetime, that one is one you will not have to have again.
