Those are buffalo burgers out on Catalina. And there are buffalo out there on the Island. I’m not sure one is made from the other.
Update: January 2006. Adam and I have now flown to Catalina’s little Airport in the Sky over half a dozen times. There is a small herd of buffalo kept on the Island by the Catalina Conservancy. There was a larger herd from a film production many years ago, but they were over-grazing the island and destroying it. Now it is just a little roving tourist attraction. Needless to say, they do not regularly butcher and grind them up for burgers.
