Dave,
We DID enjoy the book "Loaded Dice". Someone (maybe even you?) recommended it when we first found the dice last year. I was totally amazed to learn that it wasn't illegal to cheat the casinos!! WOW!! (Not illegal...but it was a health hazard!)

Our West Side dice appear to be straight. 1's are opposite 6's, 2's opposite 5's, and 3's opposite 4's.

Thanks for your help!
