Good question, Elizabeth. One still summer evening I pitched my beakless tarp olnly to be awakened in the night with the wind pouring in the front end. Rather than flutz around in the dark, I just turned around, sleeping with my head towarde the low end. This was not a good solution. My tarps now have beaks which means you can get a good low pitch, especially if you have the low end facing into the wind. Also, I use a square tarp that I built to go over a hammock, but I alos added tie-outs half way up the edges. In the photo, note that those halfway points are staked to the ground, keeping the end of the tarp that was facing the wind low to the ground. My daughter and I spent a comfortable night greeted by an October frost in the AM.
