One of the bummers of bike commuting is your inability to be a hero. Obviously, it doesn't happen often, but disaster struck today. My wife was stranded at Target with the baby and our van wouldn't start. Dead battery. She called me for help.
It's easy to jump a battery... when you have a car. There's nothing to hook those cables to when you're on a bike. I had to hunt down a buddy and borrow his car to rescue my wife. Logically, it doesn't happen often enough to be an issue. But I did get stressed today trying to figure it all out.
