I was attacked on the Pinellas Trail in St. Petersburg FL 4-13-16 by 5 teenagers, sounds really close to what this guy went through. I was hit in the right side head by a blunt object fractured my jaw and cheek bones, needed 2 plates and ten screws inserted. My vision is all screwed up too, but should get better. They tried to steal my bike but I total flipped out, I had blood pouring from my nose and was screaming for help while I stood up and started walking towards them. Two other bikers that just past me the other direction heard my calls for help and came back. That's when those kids all scattered. I never fell, so luckily I didn't have any other injuries. I think they saw a 50 year old man coming and thought I was a easy target, but they were very wrong.
