From Lucia Marett, New York, NY:

I wish to set the record straight about this U.S. currency debate, as many blind people feel currency should be identifiable by touch, (notches, raised dots,or differently textured bills). Those who dispute the issue, saying that modifying the environment will make sighted people believe that blind people are incapable, had better let the silent cars do their thing. Modifications also can be helpful to sighted people and are, therefore, not just for the blind. Of the two organizations that claim to be advocates for blind people, neither truly represents blind people.
