In my database, I have a category for the type of casino with a drop down menu. The types would be:

Riverboat, Indian, Card room, Gaming, Cruise Ship, and Illegal. The database allows users to add to these and /or remove any as well. But....I was thinking of the "State" category. For the big "Cruise Ships", there may be no state, so under the state heading I have them as "Cruise". Make sense? I'm leaning to having them as a seperate collection.

My personal collect(s) have broken down like this:

Nevada
Non-Nevada
Foreign
Illegal
Other (for fantasy/fakes, ad chips, etc)

I am considering making a seperate "collection" listing for the wet chips.
