Like any other teenagers, homeless teens (and all the ragged posers and deadbeat twenty-somethings who lurk alongside them) need a place to hang, too. After getting run out of their long-held Skyline Park kingdom, the gangly crowd migrated up the 16th Street Mall to where it meets Stout Street in front of Walgreens -- but business complaints and motorcycle cops made that spot a bust as well. Today the fountain on the north side of Civic Center Park is the teen meeting place of choice. Though it's poor panhandling territory, the pillared amphitheater allows for all manner of hijinks away from the suits and tourists. At least for now.
