Who says San Francisco is immune to patriotic thrills? Not anyone who’s been around here for Fleet Week which runs now through October 8. For aerial hijinks look up from anywhere at the Blue Angels and the Canadian Snowbirds or from your box seat on the Marina Green ($55-$75). On Friday from 11-12 there’s a parade of our mighty nautical armada sailing through the Golden Gate. On the Embarcadero for the entire week enjoy tours of carriers, amphibians and destroyers, accessible on a first come-first served basis. Invite a hundred or so of your friends to a fleet party in one the private waterfront chalets.
