Salad dressing required

Today I passed a romaine lettuce field where the workers were harvesting the crop to a long conveyor . There were maybe 25 or so along it as it moved slowly down the rows. I had left my camera at camp... dummy... and had to drive back a mile or so to shoot my Blip. They work 3 days a week to keep up with the maturing crop. My back would last 5 minutes... tops. We see spinach, head lettuce and more things growing that are not identifiable... by me. The literature here indicates that 90% of the leaf veggies for the country come from this area (Yuma Arizona). The Colorado River irrigates all of this. The wi-fi here is in another building so I'm not able to comment, (in a timely manor). Have a great weekend all.
