Many nearby debris disks that have been resolved in scattered light show a variety of twists, warps, or asymmetries. Often these features are noted and the presence of unseen planetary companions is inferred. However, the outer regions of debris disks can be impacted by the surrounding interstellar environment. In this talk, I present scattered light observations of the edge-on debris disk HD 32297, which shows warping at distances beyond a few tens of AU. I also present a simple model involving supersonic gas drag on debris disk dust particles that explains these observations and the strange morphologies of two other debris disks, HD 61005 and HD 15115.
