Just found out my father in law (retired PD) and mother in law (retired RN) were some of the first on the scene. He shut down traffic while she tried to save him, but there was no helping. I'll spare the gory details, but it was not a head injury and helmet or not had nothing to do with it for those wondering.You can follow all the rules, wear a helmet, pay attention, be courteous, be safe ... but sometimes you just have to realize that you have no control over the "other guy."
I hate these stories.
Anyway, she's pretty busted up about it. Keep the rubber side down and watch your ass boys.
