That will be a bit of a stretch. I think your best chance will be to program the Guilford and Sunman sites maybe Lawrenceburg. The Sunman site is actually about 2-3 miles north of I-74 & St. Leon. The Guilford site is a little south of St. Leon maybe 7 miles or so. Both of those sites get out pretty good and will carry traffic from dearborn and franklin counties along with ISP district 41, 42.
I doubt you'll be able to get the lawrenceburg site, but it can't hurt to try.
