Cougar sighting on Dickey Creek Trail

I hiked the Dickey Creek trail today, and about two miles in from the trailhead I spotted a cougar in the trail ahead of me.  The trail in that section is not straight, but winds around the various topographic features, so I saw a side view of it from where I was.  It was probably 100 yards away by direct line of sight.  When I saw something move in the distance I thought at first that it was a deer.  Then I saw the tail, and I thought it had to be a cougar.  When it turned its face toward me, there was no doubt.  It quickly ducked into the rhododendron thicket and that was the last I saw of it.  I know they're out there, and I often wonder if they are watching me as I head down the trail.  But this was the first time I have actually seen one in many years of hiking.
