RR arrived on Friday and went out this morning to Donna Walker. Tracking number is 9114 9012 3080 1553 7566 11 with expected delivery of Wednesday 9/10.
From the posted comments, I reorganized the RR and removed most of what I saw as problems. There was 5 doubles as follows
Mirage - Yellow Beatles, Tropicana - Green is Better, Mandalay Bay - Latin Grammy, Panasonic & Bayer Parasite Solutions.
In addition there was one slot card from the Tropicana and a key from a Louisiana Casino. I left in one key that I don't know anything about but it could be a convention key. I didn't write down the name. I did trade out these wrong keys and added 3 keys to the RR.
I found 3 keys for my collection - one new one and 2 varieties. Thanks for the RR and good luck to everyone. Bob
