Leigh Fazzina was lost in a 300-acre Connecticut wood, racing downhill on her mountain bike looking for the main road, when her front wheel hit a tree root. She flew over the handlebars and slammed into the ground, to find herself bloodied and unable to walk…and panicking. She tried screaming and calling for help on her cellphone but couldn’t connect. Then she tried Twitter, the social networking site, hoping that one of her 1000 followers might see her tweet:

“I’ve had a serious injury and NEED Help! Can someone please call Winding Trails in Farmington, CT tell them I’m stuck bike crash in woods.”
