For crying out load, can't they just borrow a herd of dairy cows for the show? It's probably more expensive to create the artificial ones! Plus the yutes will not get the full experience without the aroma and taking some sweet stuff home on their shoes.
Besides, with that many decoy cows around a whole flock of 'em might descend on them an cause a real problem. Them people up thar eats too many beans!
Success is the ability to go from one failure to another with no loss of enthusiasm.

Since the artistically decorated cows will be raffled off for charity, I'd imagine they felt "old Bessie" wouldn't be purchased by many of the hoi-polloi. Hard to haul a live dairy cow into a loft apartment...the cows tend to protest.
We did something similar here in Columbus with giant concrete ears of corn. It was actually kind of fun to see them stuck in odd places all over the city, decorated in wildly creative ways....
