I took this ride with friends last Sunday:

From Huntsville AL take HWY 72 East and make a left on State HWY 65 (not Interstate 65)
Enjoy a twisty ride thru Paint Rock Valley
Make a right on HWY 146 to HWY 79, turn right on 79
Make a right on County Road 17 to County Road 8 make a right....fun twisties
Continue on County road 8 back to HWY 72.

It was a really fun ride. Try it if you are in the area.
