USA Today: Since the "Summer of Love" more than 40 years ago, this liberal city and its legendary Haight-Ashbury neighborhood have been magnets for the young, the alienated, the down-and-out and the stoned - and for tourists eager to watch them.

They are calling for an ordinance to make it easier for police to clear sidewalks of what they say are aggressive panhandlers and the open use of drugs.
