Besides the cards I also have two decks of playing cards from the Mill in different colors, a green bungie from The Mill and a pen from Chinook Winds. There are also some business cards from Kla-Mo-Ya and Spirit Mtn and TITOs from Kla-Mo-Ya and Seven Feathers. Kla-Mo-Ya was tough to get to, over 3 hours each way from the hotel but a nice place!
Since there weren't many casinos I killed some time gathering regular hotel room keys from all over Oregon too. I think it was over 100 keys from probably 20+ hotels. I'll try putting scans on my website soon if anyone else is interested.
