The Indiana State Fair is to reopen after first pausing to remember five people killed in a stage collapse.
The tragedy occurred when wind gusts of 60-70mph toppled the stage where an estimated 12,000 people were waiting to see the band Sugarland on Saturday night.
About four dozen people were taken to hospital, some critically injured.
Governor Mitch Daniels is among those planning to attend a memorial on Monday morning, and the fair will then reopen.
The fair cancelled all activities on Sunday as officials investigated the accident and tried to field difficult questions about whether the tragedy could have been prevented.
The accident was the worst at the Indiana fairgrounds since an explosion killed 74 people attending an ice skating show in 1963.
