The Kansas State Fair Board agreed Tuesday to take bids on some construction and building upgrade projects on the fairgrounds, including a long-delayed estimated $2.37 million project at the Expo I horse exhibition center. A few should be done in time for this year’s state fair, and others – including the Expo center – won’t start until it’s over. Even then, however, at least two buildings on the grounds that are currently closed to the public – the Capper Building and the Bison Arena – will remain so, as will the Encampment Building dormitories. Most of the Fair Board took an hour-long tour of the grounds Tuesday morning, before going into a several-hour retreat and then holding its May board meeting.
