Just back from 2 days in Las Vegas...Hard Rock has one key out, they say the other four will be released later....The new Harrahs Las Vegas keys have all been sent back to the manufacturer because they didn't work...they are back to using the old keys..Anyone have a CARNIVAL TOWER to trade? I have an extra MARDI GRAS TOWER to trade for one....I have the new Fitzgeralds and El Cortez slot cards and the new Hard Rock room key to trade.....An updated Casino Room Key book is in the wind. Please send me any suggestions on how to improve the old one, besides updates....if I like your ideas I will do it...Jackie Gaughan autographed this room key and slot card for me....
