Organizers of a weekend pro-military protest in Berkeley say they want the city to know how much a boycott in support of a contentious Marine recruiting station is costing.

Hundreds of leather-clad bikers rolled into town on Saturday to rally behind the Marines, whose downtown office has long been targeted by anti-war demonstrators.

Protest organizer Doug Lyvere of the group Eagles Up said he will present a stack of receipts to Berkeley business leaders on Monday to show how much money his group didn't spend in the city.

Lyvere said the bikers will boycott Berkeley until the City Council apologizes or is recalled for telling Marine recruiters in February they weren't welcome.

Council members eased their stance weeks later but did not apologize.
