City of Princeton issued the following announcement on July 10.
It is with great sadness we must announce the cancellation of this year's Bureau County Homestead Festival! We have been holding on to every bit of hope we could proceed with our annual end of the summer event, but after much forethought, we decided continuing with the celebration as planned would unnecessarily risk both community and those attending this year's festival.
