One of the most viewed displays at the Iowa State Fair will peer into the future and celebrate the past at the same time as the popular butter sculpture exhibit features characters from the "Star Trek" television series.
Each year Sarah Pratt creates a cow from 600 pounds of butter for the butter cow exhibit. The refrigerated case also features a second scene which has included Elvis Presley, a Harley-Davidson motorcycle and Neil Armstrong's walk on the moon.
This year standing next to the cow will be Captain Kirk, Spock, Dr. McCoy and Uhura in two scenes on the bridge of starship USS Enterprise to commemorate the original "Star Trek" television show's 50th anniversary.
The Iowa State Fair, which attracts more than a million people a year, begins Aug. 11.
