Well, you can start with: George W. Bush Retirement Rancho Crawford, TX But seriously . . . I have found, over the years, that the best free source of real and usable addresses -- not agents or mail-handling services -- are the 20-or-so Who's Who books: Who's Who in America, in the West, in Business, of American Women, etc. All the listings (about 1.2 million, I believe) have a mailing address. The publisher, Marquis, actually makes them available on line, but for a stiff fee: $1,600 a year. This is a great source for finding people with fake degrees. Marquis gives potential customers a one-hour 100-search free trial, but after that, you have to pay.
Actually the typo was that I meant George W. Mush, the famous Iditarod racer, who tired of the cold, and retired to Texas.
