yep! thats true! the helmet not only protects our heads when we fall but it protects us from killer foliage. in tallahassee we have lots of canopy roads...made of oak trees! and what do oak trees have? ACORNS! those things hurt when they fall off the tree branches and whack you on the head.
we also have lots of low branches. i just lean my head down and let my helmet take the beating or brushing from the tree branches.
