Obey the mi state laws on riding (no state highways, shoulder regs, speed limits, trail permits) and you should be okay. I have ridden in that county for several years and have run into the sheriff at least once all all he checked was that the MI trail permit was current. I don't know if the county has officially ATV designated roads yet, but I believe that that is in process. In the meantime use good judgement, respect landowers and should be no problem.
