This is what it would be like if you were living at home with your parents and they left town. Whistles, a live band, and crazy people tossing drinks all over the place. I would say you have to show up here with a slight buzz already. The music and chaos can be a bit much.
They actually had a live band going which was unexpected. I think they were called the crashers or something like that. You could tweet them your request and they would hook it up. They had about 10 security guys walking around though. That part was a bit weird. You will definitely get a huge mixed group of folks here. All age and professional ranges. Its was a fun time.
