I was in downtown San Francisco the other day. While I was standing
at a crosswalk waiting for the pedestrian light to change, I noticed
on the pavement, just beyond the curb, a stenciled likeness of GW
Bush, in yellow on the black pavement, above the text "One term
President".

Now, it seems to me that this is an extremely effective placement of
the message. When people step off of a curb, they naturally look down
and pay attention.
