Not specifically a TG oriented event, but definitely a TG friendly event! Learn about different kinks and lifestyles in what is undoubtedly one of the most accepting events I've ever been too. Great people all wanting to talk and share their experiences, and very open to learning about other people's experiences as well. Attend just one day ($10 for Friday, $20 for Saturday or Sunday) or for the whole weekend ($30). Rooms will undoubtedly go quickly, so book a room while you can.
