I had lighted deer in my yard for Christmas a couple years ago and had the antlers swept back. To me it looked more like it was flying. My young niece came over and right away told me they were backwards! I think she was 8 years old. I looked it up and ended up flipping them around. Thinking, after all, they’re for defense, not flight. I don’t really know how they should go, but I got rid of those deer eventually :-)
