Look at the post "38 mile ..." posted by Bill Hiem. It starts at 11am from Lascassas Baptist Church. Lots of hills in Lascassas but good scenery! Have fun!
It looks like you could go Jug Creek/Owens/Puckett/Phillips/Sherrilltown/ to save some miles. OR even shorter would be Jug Creek/Cainsville/Simmons Bluff. I haven't been on Owens etc. Please report back if you go that route. Simmons Bluff goes through unless there is new construction underway. That could be the fall back route if the others don't work. I'll have to miss or perhaps ride at 2:00 if the ride gods shine on me.
