Since 1993, when the Lesbian Avengers organized the first Dyke March in Washington, D.C. at the March on Washington, and then again in New York in June, dykes have come out to demonstrate for lesbian rights and visibility.
Every year, thousands of dykes march down 5th Avenue to Washington Square Park on the Saturday before the NYC Lesbian and Gay Pride Parade. Drummers up front near the banner rally the marchers out into the street and keep the rhythm going all the way down to the Village. Signs proclaim political and personal slogans like "I'll be satisfied when every dyke can be out" and "I'll be satisfied when my mother can say the word lesbian." We've seen giant lesbian puppets, a swimming pool complete with bathing beauties pulled along by strapping gals, SuperDyke in a rainbow cape, and of course: the fabulous marshals, those tireless and dedicated dykes, who lead the march in the front, run down the street blocking the traffic on the sides, and bring up the rear of the march.
Dyke Marches are held all over the world. San Francisco has been full of marching dykes since 1993, and hosts a fabulous Dyke March web site with links to many dyke marches in the US and in other countries. In 2003, Mexico City held their first Dyke March - congratulations, lesbianas!
