We went to an natural preserve where the endangered red cockaded woodpecker frequents.  I got tired of walking.  Every step I took would be one more step back.  There was no loop on the trail.  My friend kept walking and when he came back, he reported seeing a pair.  The board walk went through swamp land.  The woodpeckers like long leafed pine.  To me, the trees were odd because most of them went fifty feet up until they had branches.  My friend said they were common in this area.  I kept looking but did not see any of those woodpeckers although I was happy he saw a pair.  I was glad when he returned to the car and we returned.  I was ready for a nap.
