Has anyone been to one? I'm supposed to be going to one at the weekend. I have really mixed feelings about them, especially after watching the documentary about them a few months ago. The main reason I'm going is that a lo that we may end up being matched with will be there, but I'm planning on going with an open mind. I'm not really sure what to expect, or if I even think they're a good idea. I guess I just wanted to hear from anyone who's been to one and see what peoples opinions on them we were?
