I don't think there is a square inch on my shins that isn't scar tissue. The worst pedals were the Huffy pedals that looked like dull saw blades. I stripped an easy 4 inches about an inch wide off my right leg with one of those. Wrecked off a jump. My mom fainted when I got home. Nothing the Doctor could do. Massive scar that is now, at 52, purple and so thin I can see my shinbone
