Ya know, I really do not know? We stopped by the cage Tuesday afternoon, and had a bunch of chips to "cash in." I just emailed someone from the forum here with all that we knew. "Jimmy Mac" made a post on here not long ago, if someone can pull that up, and post, it might give more info to others. Sorry, but, this is all that we know, other than that we were told the last day they would accept the "LE CHIPS ISSUED IN 2007", was, I believe around Dec. 19, 2008? Not sure to be honest, it was rather a "shock" to us, and we had a bunch of people with us at the time.
