I am currently in the process of developing a personal rain-deterrence device which I have code-named "umbrella" in order to keep the Chinese from divining my secret system.
I would welcome private investment from obvious forward thinkers such as yourself to bring my device to market before the "08 Olympics.
While your suggestions of "roof" and "retractable canopy" are imminently sensible, I believe there is much greater profit potential in my invention due to the potential of higher unit sales of personal protection instead of mass protection.
I can be reached through Tonyumbrella.con.
I don't think Madam Zhang will be able to stop the "drizzle" with her "crack force".
Better women have tried, all have failed.
