merlin that sounds like a pretty serious climb. Looked like there was some really good riding in that area in general. I went over there for the first time during the Greenbriar Classic.
LowCel I've heard that hill isn't as easy to access now, due to the gates and all. I've also heard coming down it is almost as bad as going up, again due to the gate at the bottom.
ENEMY it is near KC, just across I-64. Good luck!
