Warmer than Florida?
Oh, Florida is probably warm enough. For some reason I thought you lived somewhere snowy. Not sure what the details of the laws are like there, though.
From wiki:
In the United States indecent exposure is defined by state law as exposure of the genitals and/or the female breast in a public place and may in some states require evidence of intent to shock, arouse or offend other persons. Public place is any place where the conduct may reasonably be expected to be viewed by others.
The offense is variously titled "indecent exposure", "sexual misconduct", "public lewdness", or "public indecency". It is a criminal offense in all fifty states and is punishable by fines and/or imprisonment, and in some states a conviction results in having to register as a sex offender.
From farther down that exact same Wiki page (http://en.wikipedia.org/wiki/Indecent_exposure) :
Exemption for breastfeeding of infants
A majority of states exempt breastfeeding mothers from prosecution under these statutes. [3][4]
U.S. Public Law 106-58 Sec. 647. enacted in 1999, specifically provides that "a woman may breastfeed her child at any location in a Federal building or on Federal property, if the woman and her child are otherwise authorized to be present at the location."
