Paul the RR arrived today. Yes, as Paul Sax said, there are over 10 dupes, and some are even triples. That is too bad. I guess some people don't care what they toss in. I got my room key RR back and it had bent and "warped" keys in it. I don't have an answer. I took 4 of the Expo cards Paul added, and I replaced them with new, New Mexico cards. I added 8 for your trouble. Thanks Paul, Pat Lamb
