Just returned from the 11 mile trip to Wytheville and a visit to MacDonald's to steal their free WiFi.  Purchased 4 Duraflame logs and a large folding camp chair.  Sky is completely crystal clear and blue, which suggests a very cold night.  Typically, cloudy nights are warmer.  Picked up a cheap thermometer for inside the tent.  I hate second-guessing the temperature.  Called sister Debra from town and sent friend Nancy a text that all was okay.  It is strangely warmer now than it was earlier, although the wind has died down quite a lot.  Just gathered tonight's firewood and broke a sweat!  Popped a Carona and set up my big chair.  Listening to the last bird calls.  The barred owl I heard last evening never came any closer.  6:30 p.m. - Sun has totally disappeared below the horizon and the new thermometer says 54 degrees.  Holding off on lighting fire.  Very quiet - except for falling acorns.
