I agree with what IrishRogue said about speaking directly with the people at Rays and educating them rather than threatening them with a boycott. In my experience, Rays is usually genuinely concerned about food sustainability issues. For example, they have local, organic grass fed beef on their menu and I believe that at least one meat CSA operates out of the Ray's parking lot. Perhaps they just need some education rather than threats.

IR, send me a PM if you want someone to head to Rays with you. Would need to have some current data. Anyone here want to provide that?
