The easiest way would be to go to a bar or use a dating website aimed at gay women. Seems more reliable than trying to hit on women you guess are into girls.

My gaydar is permanently in need of repair... I have quite a hard time differentiating the gay girlies from the straight ones unfortunately... But I guess that's because we don't all fit stupid stereotypes :) Sometimes you just get a vibe or a feel about a woman... sometimes it might be more obvious, which is where some stereotypes will come in. My usual ploy is, if I can't imagine her with a man, it's usually for a reason. Vague I know.. Probably why I have such crappy luck with the ladies lol.
