A few members of the horrible, America-hating SF board of supervisors want to keep the Blue Angels out of the city, because "boo hoo they're loud and dangerous and they pollute the air a bloo bloo bloo".
Good thing they've made little to no headway in this area.
So far they've been held at bay by the fact that Fleet Week is a huge draw for tourists, allowing them to temporarily slake their insatiable hunger for tax dollars.
