Golden Gulch is Black Hawk--they use the same card at Golden Gates. They give you ONE and put your picture on the back of it. You sign up at the Gates, and pick it up at the Gulch. Or if you wait around and play a while, someone will go and get it for you. They walk by you every hour and ask to see it, giving you points on your card. They do NOT go in the machines. There is a mag strip as well as the player picture on the reverse. You will NOT find these laying on machines around the casino. Pat
