Seems like a lot of cooks are also CBJs, but if they are not judging at the competition then their being a judge is irrelvant.
If they ARE judging, staying too long at one site is not a good idea (as most others have said). As has also been said, wearing something (a hat) that links you to a single team can cause misconceptions that we don't need.
