Well, this seems to look like it's becoming a long web. It seems it might be best for similar aged groups to hang out, as I'm sensing there is some varied age ranges that are represented. I'm 28, and wouldn't mind hanging out with those 23 - 35. As far as Opera Bay is concerned, I do believe it's still in the Opera Bay building (the one that looks like a flattened version of the Sydney Opera house in Puerto Madero... and hence the name).
