There is a Detroit area club (as well as a Chicago one, depending on where in Michigan you live. Hope to see you in Vegas in June.

The "Official" guide has pictures of some of the chips and covers Nevada and other states but does not include LE's while TCR tracks only Nevada chips but covers them all. While I prefer TCR, I have the Official guide as well and have found it useful. TCR will be kept up to date yearly; I don't know if Wells and Campiglia are coming out with a new edition.
