Philadelphia

Some people would say that Philadephia is the home of equality for gays and lesbians.  Certainly this perception is not harmed by the city being the site of the global Equality Forum (formerly Pridefest America) which is held in April/May each year.  Philadelphia's Equality Forum is a celebration of the diverse world of gay, lesbian, bisexual and transgender culture. The week-long extravaganza deals with many major issues confronting modern gays and lesbians and includes great nights out.

Having said that, it pays to be careful if you are out and about in any city.  Whilst the area around Center City is vert gay-friendly, other areas might not be quite so liberal.
