Hi Jim,
Nice report and nice web site.
Here is a little help for your Carnival inlay ID's. It was posted while you were gone. Information is courtesy of the man that is the boss of the "Fleet Casino Mgr" that you met. John Long is in the process of preparing a Carnival Column that will appear in Poker Digest.

Mardi Gras 1972 Yellow
Carnivale 1976 blue
Festivale 1978 white
Tropicale 1982 green
Holiday 1985 red
Jubilee 1986 brown
Celebration 1987 purple
Fantasy 1990 orange

Scanned are 2 fractionals that are only on the Celebration and 1,000 each made at this time. Sorry, all of my fractional traders are gone
