If you send a wedding invitation to the President, you will receive a congratulatory letter from him and the First Lady! ps, it works for mickey mouse and queen of england too. Great for scrap booking or memory box..i had no idea you could do this but its so cool!
If you're in the midst of gorgeous scenery, why not try a ceremony in the round? Not only will your guests get a unique view, but you'll also be (literally) surrounded by your loved ones during that special moment. Source
