MITCHELL, S.D. (AP) — City officials in Mitchell want assurance that new domes for the Corn Palace tourist attraction can withstand South Dakota's weather.

The domes are part of a $7.2 million makeover of the building that's billed as the world's only palace dedicated to the grain. About 200,000 tourists visit each year.

The makeover was to be finished last month, but The Daily Republic reports that completion has been pushed back a couple of months. One of the reasons is the new domes, which were seen visibly shaking during recent strong winds.

Mayor Ken Tracy says officials are anxious to get the new domes installed but want to first make sure they can stand up to wind and snow. He hopes that can be verified in the next week.
