Rivara already engaged in surveying and lobbying

"What is quite revealing is that one of the authors, Rivara, was already engaged in surveying and lobbying for helmet use before this study was commenced."

Do you have a reference for this? I need one to firm up the Wikipedia Bicycle Helmet page. Thanks! 213.131.238.25 17:20, 15 August 2007 (BST)Dermot

Thank you very much, Guy.
No problem. There are two important facets of this study: one, that it shows Rivara was already involved in campaigning at the time of the 1989 study, and two, that he was aware (or shold have been aware) that the assumption of usage rate in the 1989 study was wrong. JzG 13:55, 21 August 2007 (BST)
