I had 3 years of German in high screwall, don't remember much. I should have taken Spanish. I hired a few Mexican roofing crews when big hail storms came. At least each crew had an English speaking translator, sort of. I loved them, hard working, would work 12 hour days if I had the work for them 6 days a week. Many want Sunday for church. One crew rented a cheap motel room, 2 queen beds, for 6 of them, they ate in the room, don't know what.. Loved them compared to the average white roofer.
