Report 29148: Backpackers startle a figure with long white/blonde hair watching Boy Scouts at Grandaddy Lake

I was backpacking with my brother and four nephews at Granddaddy Lake.  We were setting up camp, and my brother and I went off to find a tree to hang our food on.  We were getting closer to a group of boy scouts we had been hearing while setting up camp.  My brother was looking into the trees and I glanced over towards where the scouts were, when I saw something with long white/blond hair was staring into their camp.  It must have been startled by our presence because it took off running extremely fast toward the marsh area.  I remember very vividly the hair bouncing as it took long strides.  The lack of noise that it made along with the speed startled me to the point that I unbuckled my gun holster, concerned for our safety.  My brother didn't see what I did because he was too concerned with why I was going for my gun.   From the way it was running I could tell it was on two legs, although I couldn't see below the shoulders due to the vegetation in the area.  I would estimate the height about 6ft.  The odd thing for me is that I didn't go over to the location to look for prints, although it was standing in a very wet area.  It was bothering me badly to the point that we went over to the scout’s camp and asked if anyone in their party had blond or white hair.  None of the scouts had blond or white hair.  Everyone in my party told me I was crazy, but later I found out it was because they were scared and didn't want to think about it.
