There was a place on my first George Sound Track where I lost the track and absolutely couldn't follow it.  I had eliminated all possibilities except for one and even then, I could look down the two-meter tall drop and tell that the track wasn't there.  Once I was down the drop, I found the track, even though 30 seconds earlier I had been staring at the track.  That section of the track is that hidden.

I didn't think I would get confused again but I hit that section again and said, "Where the &*($# did the track go.  This time I found it quicker and had to climb between the downed trees and the drop.  I love this place!
