As best I can determine, the pit stop is below. There's more than one set of striped water tanks; I took Mary's directions and double-checked them against Mapquest and GE (kmz attached). Damascus road is on the right (sideeq, sadiq, various spellings--the sadik district is beyond Damascus), and 5th ring road is just above the tanks. Haven't found gharabally street or the feed lot yet, and I'll stick with my original estimate for the racetrack.
