There might be some strings attached! And it's not the same thing as buying what we think of as stock that's going to give you a sweet financial return. According to a story I read in Yahoo Sports today, stock in the Packers isn't an investment. It doesn't rise or fall like something you'd buy from a broker. Buying Packer stock only gets you a certificate of ownership, nominal voting rights, and the ability to tell your friends that you own a sliver of the Packers. And yeah, the purchase comes with a TON of rules. You can see the 12 pages of rules and restrictions at http://packersowner.com.
