This was a dream I had about a road trip through a desert somewhere. I was moving along pretty good but then ran into some commotion ahead up the road. I slowed down until I couldn't drive any further... Obstructed by police activity and people getting out of their cars to see what was over the crest of the sandy embankment on the south side of the road. I parked and got out. A flood of people crowed around the top to see the mass of arabs gathered down the valley.
