Parked for miles along the highway were hundreds of trucks carrying hay and what looked like feed. It was on the outskirts of town, near the camel souk, so perhaps it was all to be sold to camel owners and herders. If so, that was a lot of food for them!
Patti linked me to an interesting article about how the Saudis are buying up farmland in the American Southwest so they can export things like hay back home and save water here http://www.cnbc.com/2016/01/15/saudi-arabia-buying-up-farmland-in-us-southwest.html\
