In about 4 ½ miles the arboretum trial at Watoga makes a loop through ridgeline and creek gully vegetation and everything in between.  It is a great sampler of the range of plant life that covers these mountains.  However, today was probably not the best day to hike it.  There is a fair amount of up and down so we worked a little bit, the trail started out though dense rhododendron thicket, but the real factor today was the humidity.  Five minutes into the walk sweat is dripping from my hairline.  My glasses repeatedly fog.  My shirt sticks to me like a second skin.  I found it difficult to appreciate all that was beautiful around me when I was sure I was just going to melt.  The trail leveled out, the thicket opened up, and a bit of breeze began to move.  Ah, relief.
