A metallic replica of the world’s tallest corn stalk is one of the first things people coming to the Washington County Fair will see this year. The nearly 32 foot tall stalk commemorates Don Radda’s 1946 world record. His daughter Julie Zieser went up in a boom lift yesterday to place the re-bar tassel. Zieser says her husband Wayne is going to start working another replica to be placed at the Iowa State Fair next month.
