Go and have fun. I have only been to one bar that was hosting a drag show but there where as many men as woman. Straight, gay, lesbian and me in my skirt and heels but everyone was really nice. It is still a show/entertainment for everyone just like going to a bar to see a band. The reason the GG's know about these events is because the bars advertised the event publicly not just to certain types of people.Now you need to ask them if they should help you dress up for the event!
