A 28-acre parcel of land  in the area of Lennon and Dutcher has fueled speculation that a casino might be headed to Flint in the shadow of Genesee Valley Center. The buzz has been building since the October land sale.  The developer still has options to purchase adjacent parcels that could double the size of a potential development.  The land was purchased by Joanne Kemp of Macomb County.  She could not be reached for comment about her intentions for the property.
