I'm pretty excited about this, do you know from which approach the summit is officially accessible from?
I had ridden about 3/4 of the way up from the Hick's road side before acknowledging the no trespassing warnings and turning back around. From what I can remember, the steep part of Hicks and Mt Umunhum road combo was probably the most difficult climbing I have ever done, but that was back when I had a 25 in the back and hadn't done anything too comparable. Can't wait to get to the top.
Per the direction of your route, I do remember the decent down Umunhum Road being pretty brutal due to the road condition. Although seemingly more painful going up in the clockwise direction, is that something you would even consider?
