Salim Abu Ar-Ru'us 
Near the well we climbed a dune and Salim immediately pointed out a dune near the first khor, Khor Abu Gabr, about six straight miles away. I was astonished by Salims knowledge of the country and asked Khamis how he did it. He replied, "He has lived here since he was a little boy. He has a good heart and a good head. Some men forget, but Salim is a correct man and when one lives in a place all the time, winter and summer, he must know the place or he dies."
