Butter Cow to be Joined by Butter Version of Star Trek Characters at State Fair

DES MOINES, Iowa -- One of the star attractions of the Iowa State Fair is beginning to take shape.

This year, the annual Butter Cow will be joined by a butter version of the crew of the Starship Enterprise from "Star Trek." The ship's captain, James T. Kirk is a fictional Iowa native.

"This is butter Spock," said Sarah Pratt, the butter sculptor. "We were joking that it should be: live long and butter."

Pratt says this is the biggest sculpture she's ever attempted and is waiting on another butter delivery this week.

As long as it's on time, the sculptures will be ready for opening day.
