I'm heading out there this afternoon and will pay attention to what side road it's on and how many miles from the turn off at hwy 35---it's very easy to get to and I'll have exact directions--
from your area, it would be east on I-30 to the Knox turn off, then south on Hwy 35, thru Knox and on south almost to the Tippicanoe state park---I'll post the side road number later today---it's the best range I've ever seen---John
