There's something downright lovable about the "Scottish Angus Cow and Calf," the massive bovine bronzes that reside on the south side of the new Hamilton Building. They're not as obvious as "Big Sweep," the giant ode to housekeeping at the museum's entrance -- but that's half the fun. The cow and calf seem happy grazing far from the limelight, as if there's nothing they'd prefer to do than lounge unobtrusively on the grass and let little kids scramble all over their hides. Their gentle, organic presence is the perfect complement to the hard lines of Daniel Libeskind's architecture -- and a stylistic reminder that Denver will always be the cowtown we love.
