I already tried Berkeley Bowl -- which has a truly awesome butcher's counter -- and the odd little "strange creatures" butcher shop on San Pablo Blvd. It occurs to me that if I wanted to substitute pig knucklebones for the traditional sheep, I could buy a load of ham hocks. (And then have flavorings for the next five years worth of split pea soup.) But lamb carcasses evidently normally arrive already cut off above the ankle. Over the years, I've learned to sense when a specific task is likely to suck up time that could be spent on other things more productively. We've got over two dozen games on tap -- and I've already eliminated some items for playability reasons (e.g., potential for injury) or awkwardness of props (like the "balance on a barrel" game).
