On the home page of the Chip Guide on the left side under the "::Features" heading is a Casino Search button. It searches across all the entries in the Chip Guide and is very helpful in narrowing down the possible locations for a chip's home. The search tips below the entry box is really important. For example when I put Dude Lounge in the search box I got back a bunch of places but when I changed it to +Dude +Lounge it returned only the Montana location.

Just trying to be helpful. I have only been using the Casino Search for the last few months - I just didn't figure out how to use it before.
