Red Gym Chat

I'm thinking about leaving a day early for a thing I have in Syracuse on Saturday morning and would have Friday night open to play at Reds. I want to spend some time in the gloryhole, but the Black Out thing has me intrigued. What time does this happen? I like the idea of groping and being groped in the dark. What is the normal etiquette? Is it permissible to go down on someone where/when you find them in the dark?
