The white trail in Wildcat is one of my favorite trails around. It's more rideable heading from yellow near the reservoir toward the hawk watch and then down toward the graveyard. In the other direction, some of the climbs are not doable for me, including one that is a straight up wall, and there are one or two rock features I've never quite made. I remember the first time I was on that trail, and saw some of the rock gardens there and was like "why did I even bring my bike here, nobody could ever ride this." It makes it very worthwhile when you finally clear it and then you feel like a God.
There are some newer and easier trails on the other side of Green Pond Rd, and also north of Wildcat. Not sure what I'm doing tomorrow yet, but I'm at Wildcat 2-3 days a week and would be happy to show you around.
