from the new times 2011 best of miami:

best place to people-watch: biscayne boulevard near i-195 during ultra music festival
"there's nothing more entertaining than watching underage kids escaping from late-night raves and wandering near the bus terminal during ultra music festival. typically standing around and waiting for someone to give them a ride home, these kids are easy to spot even in the darkness: lanky, sweaty teens wearing shit-eating grins, loads of rubber or string bracelets, and such a mix of fluorescents, patterns, and ill-fitting spandex accouterments that make them look like refugees from an american apparel store in the harajuku district."
