Bill Webb has identified the ridged glass building used for World
Securities in the "Probe" pilot. (It was also used for Timothy
O'Toole's building in "Moment of Madness.") He said it is the Bank
of America Center building in downtown San Francisco. Bill added
that he plans to take some digital pics of it whenever he gets back
to San Francisco again.

Now all we need is to identify the flat glass tower that was used for
World Securities in the rest of the SEARCH series.
