well shucks! god bless these gals for enhancing the sex appeal of a transport mode which, once you've tried it, needs no further (and certainly no helmetless) endorsement. if "spokesmodels" can woo more people onto 2 non-motorized wheels, then great!, but we the existing merry pedalers, helmet-haired and obedient to [most non-obstructive] traffic laws, had better sprint for cover if new riders are only concerned about the aesthetic, and not the political or safety implications of their fetish.
