Horses and their trainers exercise on the track at the Montgomery County Fairgrounds Thursday. Earlier this month, the Fair Board approved a two-year option that would allow Miller Valentine Group to purchase the 37-acre South Main Street fair site in Dayton for $16 million to $18 million. Rezoning to accommodate the relocation of the Montgomery County Fairgrounds to Brookville could be finished within 90 days according to a fast-track plan being pursued by the city. LISA POWELL \ STAFF
