Dolores enthusiasts clean up park  Dolores Park, the epicenter of indiscriminate littering in San Francisco in recent weeks, is a lot cleaner after a Facebook drive.  The Friends of Dolores Park, a group formed after park-goers clashed with Rec and Parks rangers over park rules a couple of weeks ago, handed out more than 100 trash bags for people to pick up after themselves Saturday. The cleanup left the park virtually trash-free by 7 p.m.  "It was a resounding success," said organizer Andrew Rogers, adding that the Friends now have over 200 members on Facebook.  The cleanup campaign was originally conceived as defending "the right to party" and a "fight against ranger harassment." The group has since changed its message.  "We recognize that without respecting the park and community, we have no place for a picnic or a party," Rogers said. "Secondly, we removed the characterization of ranger involvement as 'harassment,' and acknowledge that rangers are simply doing their job as instructed by the city."  Besides the spearheading the pickup effort, the Friends reminded park-goers to refrain from urinating in the streets or among the trees, and instead use the portable toilets.  Rogers said the group has reached out to Rec and Parks supervisor Adrian Field and city Supervisor Scott Wiener to increase the number of PortaPottys from 10 to 30 and add more trash cans, as the current toilets and receptacles cannot handle the 5,000-10,000 visitors on Saturdays and Sundays.  Rogers said the Friends group was formed in response to the trash problem and ranger citations, and has nothing to do with a well-publicized video of partiers arguing with a ranger in the park.
Dolores Park-goers tone down their rhetoric and clean up the park. They say the effort "was a resounding success."
