I have rode several places in eastern KY. but have not made it to Redbird yet. I have been meaning to get there for the last two seasons. From what I understand, it can be a tough all day ride, to finish the 60 - 70 mile loop. One guy told me that they spent 8 hours on a wet day in Dec. doing the loop. I have also heard that some of the good single track has been widened by quads over the last few years. Some of the climbs and decents are tough by B rider standards. Let me know how it goes. I will make it there soon.
