DOWNTOWN LOS ANGELES — Driving down Fig an hour or so ago I saw a large formation of helicopters heading east to west. Some chopper I didn't recognize in front, then five or six LAPD birds, and finally five or six Sherrifs department choppers (which I don't think I've seen before). I'm suspecting it was for filming; there's something going on over on the other side of downtown involving tanks and gunfire and such (or at least that's what was billed in the filming announcement), so it might well be that.
