The challenge was long exposure. I tried limbs blowing in the wind but it was too windy.  I only ended up with a smear.  So tried night across the Pomona Dam.  The camera wouldn't work and went back to the house and then it worked.  Went north a mile and waited and waited for a car to come buy.  Finally Dennis drove down the road and turned around and drove past me so that I wouldn't freeze to death waiting for traffic.  Good sport.
