There was a strange scene the other night.. My boyfriend and I got off the EL at 40th St. around 12:15 AM or so and there was this huge mass of teens walking up the sidewalk/street from chestnut to market..There was a strange tension in the air and there were a few bike cops around calling for backup on their walkie-talkes.. It looked like this huge gang fight was about to break out.. We walked through the crowd and ducked down a side street and were just really curious as to what was going on, and if anything really happened afterwards ? thanks
