I too am just back from Laughlin and here is some information:

The Pioneer has discontinued their "tier levels" of slot cards. The only one being used is the brown ROUND UP CLUB card....the others are obsolete.

The Colorado Belle issued ONE BOX of 2001 cards....and plan to do more special event cards in the future.....I was there last week and they are all gone.....BUMMER, see the picture here of one I got early in the month.....no traders.

The Riverside pictured here has an interesting "BOWLING" on it, no traders

Avi Resort and Casino is a bit out of the way but well woth it. Very friendly and they have pretty cards. This one is OLD and the only one I have, no traders.

The green Ramada Express is obsolete but this one is for trade.......

I will be going back to Laughlin in February and hope to find some new goodies. If any of you would like to trade non-Southern Nevada cards for 8 different Laughlin cards, let me know Thanks Jim Munding
