I taped my sticker on the inside of the back window, so it would not fade in the harsh midwest winter! I plan to leave it on until January 2009!
My 18-year old son, bless his heart, keeps his 'W' oval sticker on the back of his black Edge truck .... right next to the SoCal sticker! He voted for the first time in 2004 and made a whole page in his senior scrapbook devoted to his voting for GWB ... and he had to turn it in to the ultra-liberal English department for final grading. He got an A, too.
