Rise and Set Sun Visors were invented by me, Carolyn Barnett Porch.  I drive many miles every day in the West Texas sun, and found the sun visors attached to my vehicle sorely lacking.  Therefore, as is often the case, I was forced to invent a solution.  If you have questions, or better yet, would like to assist me in marketing Rise and Set Sun Visors, please contact me.  I have a patent pending, and would especially like to sell my product to a manufacturer of vehicle gadgets.  I can be reached at carolynbporch@suddenlink.net or by phone at 325 338 1123
