There are those who would argue that any farmers' market offering a didgeridoo brain massage is really more a festival for hapless hippies. The Mill City Farmers' Market gets away with it, mostly because everything else the market offers is so irresistibly perfect. Come for the all-natural Chicago-style hot dogs, the pork sandwiches, the fresh-squeezed juice, the cooking classes, and the just-harvested vegetables piled high in front of the farmers who plucked, cut, and gathered them. And what the hell, cap it off with a brain massage.
