walking back home from a restaurant on 5th ave south of the arena around 10:30. the bieber concert must have just let out because traffic was backed up for several block south on 5th and throngs of tween girls and their parents/guardians were streaming down the sidewalks, trying to get cabs, getting on buses, walking to and getting to their cars: i.e., trying to get home. gridlock and honking horns.
i walked up to flatbush and then down dean street toward my home on dean between 6th & carlton. there was a huge crowd of bieber fans massed on the corner of 6th & dean. at least several hundred, apparently waiting for bieber to get in his tour bus and leave. i kept walking home, embedded in a crowd of fans probably heading toward the surface parking lot on dean between carlton and vanderbilt aves. i went into my house. at about 10:45, i heard lots of screaming coming from dean street (if you've ever seen the girls lose it for the beatles, this was very similar). and, i could clearly hear all of this with my double-paned windows closed. very loud. so, i went to my front door that faces dean street in time to see what was probably his tour bus roll by with a police car with lights on trailing it, and the girls all screaming and running down the sidewalk. i regret not having a video camera handy. there were literally HUNDREDS of girls screaming and running after the bus.
