One weekend last spring, we were riding our bicycle around White Rock Lake with our faithful wife and our sometimes faithful toddler son when we chanced to see a well-made sign standing in the grass, along the lake's shore. The sign read, "Free Advice." Near it sat two men in comfortable lawn chairs. Between them, on the ground, was spread a blanket. We stopped, thinking it was some sort of performance art. Turns out, Roderick MacElwain and Neal Caldwell have been doing this most Sunday mornings, weather permitting, since 1996. And it is not performance art. MacElwain and Caldwell are gainfully employed, somewhat eccentric, very thoughtful fellows who enjoy giving advice on subjects from plumbing to marriage to large-animal veterinary medicine (all fields, by the way, in which they do have experience). We and our wife that weekend wound up posing a question that can be summarized as, "What should we do with our lives?" We were not disappointed with the advice we received.
