Why are helicopters hovering over San Francisco? Does anyone have any idea what they were doing? There were at least six, for at least half an hour, spaced wide apart, seemingly just hovering. A friend said they were at it last night, too. They're pretty loud, and the one near me was flying relatively low. I couldn't make out details. Something Mint-related? I can't find anything on the news or Google.
