On the other side:

We went to the State Fair of Texas and the "Real" milk people had an outdoor booth where you could 'learn to milk a cow.' It was a fiberglass model, with a rubber like udder and all you had to do was squeeze the teat to open the flow of water!  It was the least real milking demo I've ever seen. The Borden folks had a booth (indoors) which featured a live Elsie the cow and Beauregard calf lying down (comatose?) in separate little pens. They looked drugged. You could buy a bottle of  milk (white or chocolate) for $1. It was probably shipped all the way from WI or somewhere. BTW, the in-state milk producer/sellers had no gimmicks, but were quietly selling their milk and ice cream in the food building.
