My contribution to the education of American cyclists:
I have created a trifold pdf brochure on bicycle helmets and safety. I have borrowed liberally from the European Cyclist Federation. It is in PDF format. Please let me know what you think. I am publishing it under the Creative Commons License; please retain the url if you re-use this. Right now it points to cyclehelmets.org; in the future, it will point to a USA-specific site.
