If she has a favorite author maybe you could find a signed copy of her favorite book. Take her to see her favorite band or singer and arrange for a backstage pass. If she has a collection of something find her a really special piece in the highest price range you can afford. Write her a letter telling her how special she is to you(even if you buy a gift do this anyway, she will be touched).Rent a billboard and tell the world how much you love her! Call a local radio station and tell them it is your aniversary, request a song that is meaningful to you both and dedicate it to her.(Make sure you have someone record it just in case she isn't nearby when they play it.) Rent a sports car, limo, motorcycle, mercedes(whatever turns her on) for the day and take her out joyriding. Don't forget to take a blanket and a picnic lunch! Women love anything mushy and gushy and we like it when you make a big deal out of a birthday or aniversary even if we tell you not to!
