When is National Sightseeing Day again?

Tonight's interesting calendar entry -- evidently August 23rd, 2009 is National Go Topless Protest Day in these United States:

Why a National GoTopless Protest day? Gotopless.org claims constitutional equality between men and women on being topless in public. Currently, women who dare to be topless in public in the US are repeatedly being arrested, fined, humiliated, criminalized. On SUNDAY AUGUST 23RD, 2009, topless women will rally in great numbers across the USA to protest this gross inequality in the law and will demand that they be granted the fundamental right to be topless where men already enjoy that right according to the 14th amendment of the Constitution (please see our exact legal argument on the right to be topfree for women under "14th amendment" in news section)
