Just spent the last 5 days in southern California on business and had plenty of free time in the evenings. I was able to visit just about every Indian casino in southern Calif and collect cards (about 20+ casinos between San Diego and Santa Barbara). Total haul was about 120+ slot cards and 90+ room keys among other things. I'll let everyone know what I have in doubles after I have time to sort things out and get caught up around home. It just might have to wait until after my next trip since I'm leaving for Vegas next Sunday May 3rd for a bowling tournament, coming home May 8th.
A few of the Calif casinos were pretty stingy and would only give 1 or maybe 2 cards and no blanks. Others would give plenty of cards and 2 or 3 casinos gave me a hand full of room keys.
Great trip!
