(Beaver Dam) In the weeks leading up to the Dodge County Fair, Sheriff Dale Schmidt and his staff conducted background checks on the employees and vendors working the event. The reason: to identify individuals who have travelled from outside the county or state who are registered sex offenders. Schmidt says this initiative began a few years back and netted a few offenders but all background checks since have been clear. He says running background checks has had a positive impact on fair safety. The Dodge County Fair officially begins on Wednesday.
