It's a handicap that's only mental. Read the threads/posts/bible sections (if any) about controlling social situations. My favourite is dance floor, because (frankly speaking) when the best you've got is running around shoving your crotch on her ass, it doesn't take much to steal the entire show (and steal I does).
From my observations while checking out new clubs, places that play hip-hop/rap music tend to attract a lot of HBs -- no offence meant here, but it's pop music, everybody knows the songs, and HBs go to have fun, AW, and so forth. It's great, really.
What I do is one of two things to show 'I exist', since I used to solo almost exclusively -- start dance battles and chat up people in wheelchairs. What I mean by 'I exist' isn't a sort of attention whorish act, but a different kind of opener -- you open to nobody but everybody sees you. I had/have great difficulty keeping conversations because I tended not to know much about the person, and felt that asking her 20 questions about her life was boring boring boring. Nuts to that. Anyway, dance battles are easy -- learn to breakdance (or liquid, or any 'style' -- I've actually managed to do this by 'miming' an energy ball and dancing around with it), and virtually every time (are there areas with high BDing demographics?) you are unique as a dancer. And no, you don't really need to be as good as say, Crazy Legs -- I was able to draw crowds way way back when I first was actually PRACTICING breakdancing on the floor. Looking back, it was probably that I was totally confident with myself. It helps that you don't mess up and fail to recover.
The other method of getting attention was rather subtle, and it actually took a HB to grab me and drag me off to dance right after that I realised 'oh s** people actually notice me!' -- I suppose I've been applying the 'I don't give a s**' attitude too much. Anyway, when I'm not out there dancing and wrecking havoc, I usually start chatting up the people on 'death row' -- get them to hit on girls, to dance, to do ANYTHING. Sometimes there will be men on wheelchairs just hanging out.
Now I'm not sure if this is universal, but in my experience, they get insane attention from HBs -- chatting, dancing, etc. If you befriend them early, and are geniunely caring about having fun, rather than 'look at me I'm an AW!', you can easily command the attention of all those HBs who noticed our wheelchair riding friend -- dance battle the guy. I was dancing really low to the ground, mimicking his dance moves more-or-less (like crouching down and spinning, using my hands more than my legs) -- the crowd went wild, we were having fun, and afterwards HBs wanted to dance with us. Then all you have to do is perform your number/close/eject schemes!
