Yesterday afternoon, Deschutes County Search and Rescue was called to help an injured mountain biker.  68-year-old Larry Rosenburg of Bend was a little more than a mile away from Phil’s Trailhead when he fell off his bike and hit a rock. A deputy reached Rosenburg just before 1 o’clock with Search and Rescue volunteers arriving about 20 minutes later. Rosenburg was able to walk out under his own power and was transported to St. Charles Bend for treatment of his injuries.
