Having just spent a week in the Louisville area, I would be hard pressed to call it a mountain bike mecca. I saw a few roadies, but no MTBs the whole week. Granted I may have been on the wrong side of town and missed it being totally unfamiliar with the area.
Thanks for the video Ginny Tory. I hope they can pull this off. A perfect winter get away. And the cool factor alone of riding in an old mine is pretty high. 😀 Wow their light bill alone will be enormous. I would carry my usual 2 lights and maybe a third just in case the lights go out.
