While watching the Tour de France recently, I saw a snippet of a Nike ad starring Lance Armstrong. It’s an emotionally powerful, beautifully filmed spot, as befits a multimillion dollar production by a corporation expert in the ways of persuasion, but anyhow… Closer viewing of the last part of the ad shows a couple of shots showing a huge alleycat race — large enough to look likea Critical Mass — shot in San Francisco:

even including one showing the alleycat race blowing through stoplights along what appears to be Kearny (i.e., one block uphill from and parallel to Montgomery):

Interestingly, the ad’s title of “Magnet” is explained as describing how “Lance Armstrong exudes a magnetism, drawing creatures of all kinds towards him.” Yes, and in some cases, they even block traffic!
