23 south out of Columbus.
35 south from Chillicothe into WV and along river to 64
64 to I-77 south
I-77 to just across NC line to 74/52
52 to Winston Salem then 40 east to Greensboro to 220 south.
Just south of Rockingham take 74 east to Hamlet and then 38 east Bennettsville SC and then 501 will take you right into MB.
Some 2 lane road but this is the most direct way I have found. Looks like your in the Findlay area so for reference -Its very close to 700 miles from the Walmart, Cracker Barrel, Bob Evans Outback exit that is just north of 23 on 75 if you know the area. The Shell station at that exit is a normal fuel stop for me on my way down. There is a few nice campgrounds near Wytheville, VA but can't advise on others as I usually do a overnight in Walmarts or Cracker Barrel lots.
