I'm not necessarially disagreeing but the yacht chips are the owner's personal chips which could be used anywhere (although the burgees pretty well define the location).

Do you see a difference between personal chips and casino chips? Now, a chip book author told me that they should not be attributed to any state.

So, your vote of: a) state of residence, b) state where yacht is kept, c) no state at all, is B.

Oh, I did get a 4th choice: nobody care but me!.

If it turns out that the vast majority agree on one of the 3 choices, I'll use it
