When I went on my first Boy Scouts retreat, we all had to carry our tents to an assigned part of the campground. I'd never put up a tent before, and I forgot to use any guy wires. We went off to play some field games and when we got back, half the tents had collapsed. We had to reset all of the tent frames and then attach guy wires to them. Once we had the wire stretched out, we tied the end to a spike and drove it into the ground at an angle. Those tents survived a wind storm that night.
