HBO is sponsoring the John Adams Historic American Journey sweepstakes where you could win $10,000 in cash to use as you wish or use the money to plan your own historic American journey. You can enter up to five times a day and will need codes to enter. Luckily for you I’ve done all the hard work for you and have found the codes. Here they are: POWDER, PISTOLS, BAYONET, MEDICINE and DRUMS. There is also a rare CANNON code that you will have to be on the lookout for to get 5 additional entries. Enter this cash sweepstakes by April 18, 2008 for a chance to win. Enter the HBO John Adams Historic American Journey Sweepstakes.
