 Now, around 15 to 25 sheriff's deputies from the sheriff's department will be present at the fair while it's open. Those numbers will vary depending on the security needs at the time and how busy the fair is. Sheriff Jesse Johnner says new technology like drones help them cover the wide swath of land that the Red River Valley Fair sits on. One new change for the fair this year is both entrances will now include metal detectors and extra staff.
