How can you go wrong with a party that has a giant bouncy castle for adults? A dance floor powered by one of the Scissor Sisters' DJs and New Orleans bounce music dreamboat Vockah Redu? A night featuring performances by drag super-duper-SUPER-star (and winner of RuPaul's Drag Race) Raja? And how about, on top of all that, a sex-advice booth manned by Dan Savage? What if I told you all the proceeds go to the It Gets Better Project? You have no excuse NOT to go to this. (FRED Wildlife Refuge, 127 E Boylston St, www.strangertickets .com, 9 pm, $20, 21+)
