I think I'd just like the short pamphlet. I wonder our bike club could sponsor having some printed. I can't find a local safety brochure, but it couldn't be that hard to put one together. Then they could be handed out.
Does anyone know if that sort of thing works? They might just end up on the ground, or you might make someone angry by insinuating (or pointing out) that they don't know what they're doing.
